Hey, what's up, guys? I'm Ryan from ExtremeTerrain. And today, I'm here with the Sprintex Intercooled Supercharger Kit fitting your 2012 to 2016 Jeep Wrangler JK. This is for the JK owner who's looking for a lot more power, way more than they're ever gonna get in stock form. This system is perfect for street and trail driving as it's gonna give you a ton of low-end torque by building boost fast. It's gonna make your drives more enjoyable, and it's gonna make those hill climbs a breeze. With this system, you're gonna get an increase throttle response and a lot more power. Sprintex claims up to a 55% increase in horsepower.Now, this is an intake mounted system, and it's fully integrated, so it's already filled with oil. This features a very efficient twin-screw compressor, and the intake is made from molded glass-filled nylon construction making it very lightweight, strong, and heat dispersion. Now, this supercharger has a built-in intercooler and even has a water-to-air intercooler, keeping your charge cool, and the supercharger temp cool as well. This system comes with a tuner, fuel injectors, and even some sensors. Everything you need to accommodate that extra fuel and airflow.Now, the tuner is gonna let you take it one step further, accommodating any gear or tire size changes. Currently, this system is around $5,500 on the site, making it one of the most affordable intercooled options that we currently offer. As far as insulation goes, I am gonna us give this a three out of three on the difficulty meter and expect this install to take you about a day.Now, with that being said, let's hop onto the install. Tools necessary to complete this install. Various socket extensions, electrical tape, tape measure, roll of tape, pry tool, 13-millimeter wrench, 10-millimeter wrench, 3/8-inch drive ratchet, 1/4-inch drive ratchet, 7-millimeter socket, 8-millimeter socket, 10-millimeter socket, 11-millimeter socket, 10-millimeter socket, 13-millimeter socket, 15-millimeter socket, 4-millimeter socket, short 10-millimeter socket, 10-millimeter swivel, 1/4-inch drive swivel, T30 Torx, 6-millimeter Allen, 5-millimeter Allen, pliers, channel locks, wire cutters, needle-nose pliers, plastic pry tool, a knife, flathead screwdrivers, stick magnet, scissors, torque wrench, and a 1/2-inch auxiliary bar.So before we get started with the disassembly, the first thing we're gonna do is relieve the fuel pressure system. So what we're gonna do is remove our fuel cap. We're also gonna take out our fuse for our fuel relay. After we do that, we're gonna crank the motor over. This is gonna use up all that gas that's in the lines and in the injectors. We're gonna wait till it stalls out. Once it stalls out, we're gonna try to start again, make sure that it won't start, and then we can put that fuse back in it. So this fuse is gonna be a 10 Amp. It's gonna be in this box underneath of your hood, and it's gonna be labeled M37. So we're gonna do that now. So to get this panel to open, you're gonna push these two tabs backwards, and it's gonna flip open for you. Next, we're gonna take our fuse removal tool, and we're gonna grab this one down in here. It's a little red 10-Amp fuse in-between these two ones. We're gonna pull that out because that is for ABS and our fuel relay. We're gonna pull that fuse out and just set it aside.So next, we're gonna go to the back of our Jeep, and we're gonna remove our gas cap. So after you pull the fuse out, we're taking the gas cap off. The next thing we're gonna do is to climb up in the Jeep, we're gonna start this thing and wait till it runs out of gas. First, you make sure that the Jeep is out of gas, and we're gonna put this fuse back in, and then we'll disconnect our battery on the negative side. We're gonna take a 10-millimeter socket. We're gonna loosen up this nut here, not this one. We're gonna do this one here. This is gonna loosen up the terminals so we can remove it. So the next thing we're gonna do is remove our grille. This is relatively easy to do. There's gonna be six pushpins up at the top. Then this whole thing is just gonna unclick and pull off. You will need to disconnect your lights.So we're gonna start with these pushpins on top. Show you how to do it right now. So to get these pushpins out, we're just gonna pry up on the center. We're gonna use a flathead screwdriver to get all these out. We'll just work our way across. Next, we're gonna pull the grille back. We need to disconnect our lights. You can either just turn these counterclockwise and unplug them, or you can actually disconnect them with a clip. We're just gonna twist them and let them hang in there. We'll do the same thing for the other side. Just twist that, so you can pull that whole light out. Then we can pull our grille out. So after that, you can have a series of clips on the bottom. You can just pull this whole grille out, and that will separate it. If you have a wrench, it's gonna be a little hard to get this grille out depending on where it's mounted. So you can take your front bumper off. We're gonna slide this up and out of the Jeep. Then we'll put this aside. So the next thing we have to do is drain our cooling system.So we're gonna pull our rad cap off, then we'll go underneath with a bucket and open up the drain. So your drain is on the passenger side of the bottom of the radiator. You can see it through the front of the vehicle. What we need to do is we need to turn that, we have a bucket underneath of it, and that's gonna let all the coolant out. While the cooling system is draining, we can start on some of the disassembly. So the first thing we're gonna do is remove this cover, and then we can work on our airbox. The next thing, we wanna do is take our intake out. Now, this guy has an aftermarket intake. However, if you have the factory one, you can have two 10-millimeter bolts you need to take out of here and a few clips for your airbox. You're gonna pull that whole section off. So we're gonna pull this PCV hose off of here, and we're gonna take our flathead screwdriver, and we're gonna loosen up this band clamp around the throttle body. That's gonna allow us to pull this section off. Then we can flip this up, disconnect our sensor.So after you get the intake out, the next we're gonna do is disconnect our harness. So we're gonna unplug our throttle body and our map sensor. So to unplug this, you're gonna press down on this tab here. That's gonna unlock that plug and pull that out. So now, we need to free it up from this bracket over here. I'm just gonna get behind that, and then we need to get it off of this intake. And we'll need to unplug this map sensor. This is relatively easy to do. We're just gonna press down on that little tab and unplug that. So next, we're gonna disconnect the PCV, the fuel vapor purge, and our brake booster line. So these are stuck on here at all, you can just grab them with a pair of pliers. So you wanna be careful because all these lines are plastic, you don't wanna break them.So next, we're gonna take this support bracket off. So you're gonna have two 10-millimeter nuts up here. There's gonna be two 10-millimeter bolts down here. Then next, we're gonna go over to the passenger side. We're gonna take this support bracket off. So you're gonna have two 10-millimeters up here, two 10-millimeter nuts down here. This will free up all this stuff up here. And then actually, we'll go down on the bottom side near the valve cover, we have two more tens down there. So we're gonna start up here with these two. So you may need to pull these PVC or PCV lines out of your way. In that way, you can get to these two back here. Next, we're gonna do these two down at the bottom. So I'm gonna use a deep 10-millimeter on a swivel with an extension and attempt to get these things out.Next thing we're gonna do is just free up all the stuff since we have to get our intake manifold off. So we're gonna get our vent tube out of here. Just slide that over to the side. Then we're gonna get both of these plastic tubes out. And remember to be careful because they are made of plastic. Next thing, we need to disconnect our harness, so we're gonna pull back on this red locking tab. Then we're gonna slide this towards the front of the vehicle. The next thing we'll do is remove our heater core lines where they go into our motor. So we're gonna start with this top one here. We're gonna squeeze this clamp shut or open. We're gonna slide it back off of our line. And you'll probably need to grip this line. I just twist it to break free. Once you get that free, we're gonna wiggle it, pull it back. I'm gonna do the same thing for this other line. So next, we're gonna go up by the firewall and disconnect these aluminum lines where they meet these two rubber lines for the heater core. And we also need to disconnect this other line down here as well. And before we remove this bracket, we have two lines that are still attached to it, so we need to pop those off.So, this point in time, we're gonna get ready to take this intake off. So we have a bolt back here. We need to take this piece of foam insulation out. So we're just gonna get under that, pry those two pushpins out. So we're gonna have a couple of bolts holding this in. So we're gonna start with these three up here. And we're gonna use an 8-millimeter socket to take those out. These will capture it, so they're gonna stay in there. Just need to make sure that all these are lose. Next, we're gonna do this one in the front here and do this one here on the side. There's another one back here. Then we have one all the way back here. So next, you have the support bracket over here on the driver side. What we're gonna need is a 10-millimeter socket to take these two nuts off. After that, we can pull our intake off. So we're just gonna lift it up and slide it to the passenger side, so we can get it off of that bracket. Or we can remove it from the vehicle.Now, we have that off. We're gonna take a clean rag, and we're gonna lay it over these ports. That way, we don't get any dirt in there. Next, we're gonna pull this film section off. After that, we're gonna disconnect our fuel rail line. So to disconnect this rail, we need to take this blue clip out. So you wanna take this blue lock out of here. Once we get that off, we're gonna set that aside because we're gonna need that later. So we're gonna push this white tab in. When you push that in, it's gonna allow that to come off. And you might wanna grab a rag because there are probably still some residue fuel in here, and then we don't wanna spill it all over the intake. After that, we're gonna unclip this line, so we can move it out of the way.So next, we're gonna disconnect our fuel injectors. We wanna get this whole harness out of the way, so we'll probably disconnect our cooler packs as well. So to do that for the cooler pack, we're gonna press in on this little black tab. And it's gonna allow us to unclip there. Now, for the fuel injectors, you're gonna have a little red locking tab, you need to pry up on that tab. Once you get the red locking tab up, you're gonna press in on the little black tab, and it's gonna allow us to disconnect these. So we're gonna do the same thing for the other side. I'm gonna free this harness up a little bit just so we can get a little more room. Then next, what we're gonna do is remove our fuel rails, so you can have two of them. You have one on each side, and you'll have these two bolts in the middle. We're gonna use a T30 Torx to take these out. Once we get those out, we're gonna pry up on the fuel rails, so we can get them out. Be very careful because the fuel rails are connected and also, our fuel injectors in there.After you get that all disconnected. We can pull it out of the vehicle. After that, we're gonna remove our fuel injectors. So to do that, we're just gonna pry up on them and wiggle them out. We wanna make sure that this little O-ring comes with it. If it doesn't, we need to remove it out of the lower intake manifold. So the next thing we're gonna do is install our new fuel injectors. Now, if you have any blue O-rings that are still stuck in here from the old fuel injectors, you can get those out with a flathead screwdriver or a pick tool. So we're gonna install our new fuel injectors. So you can have a red O-ring and a blue O-ring. The blue O-ring side is gonna go into the fuel rail. We're gonna make these connections face outward. What we're gonna do is just take a little bit of grease, and we wanna grease these up a little bit so that they slide in there. We don't mess the little rubber O-ring up. After that, we're just gonna gently wiggle these into place.So we're just gonna go around and get all these injectors in. Then we're gonna put our fuel rail back in. Just wiggle them all the way down, then they're gonna stop. They have a little stop built in, and then we can put that fuel rail on. So before you get this install, we wanna lube these other O-rings. After you do that, we're ready to install it. We're gonna flip this back over, just get it situated. Then we'll make sure that they all sit in place and get those bolts back in. So then you wanna torque all these to seven Newton-meters. After that's installed and tighten down, we can put our fuel injectors back in. Make sure you click down on the red locking tab. You can click on that, coils back in. The next thing we're gonna do is remove our alternator, as well as our serpentine belt. So we're gonna start by unplugging our alternator. So you'll need to push this red locking tab out, and we're gonna press down on this.And next, we're gonna disconnect our terminal up here. So you're just gonna squeeze on these two little tabs. That's gonna allow you to take that cover off. And we'll use a 13-millimeter wrench to crack this nut free and remove it. And then so we don't wanna lose the nut, we're gonna put it back on. So before we start removing the bolts for our alternator, we're gonna take our belt off. So you're gonna have a tensioner down here. It's gonna have a square cut into it. This is for a 1/2-inch drive. So we're gonna use a breaker bar, just to put tension on this tensioner, loosen it up, and that way, we can take our belt off. So to take the alternator off, you're gonna have two bolts on both sides. So we're gonna use a 13-millimeter socket for this lower one. Then we'll use a 15-millimeter for the upper one. So we're gonna do that same thing on the other side. Those are the last bolt for the alternator. So you wanna place a hand on the alternator. That way when we get this bolt out, we're gonna remove it from the vehicleSo the next thing we're gonna do is remove our factory belt because we're gonna switch it out for our supercharger belt. So, let's start pulling this off from all the pulleys and get it out of here. So the next thing we need to do is take this large gray plug. We need to make it reach the back of the motor, so we're gonna slice this open carefully, guide that all the way back, and then we'll tape it up. Once you get this peeled back pretty much to this second middle injector, we're just gonna tape all this back up and wrap the sheeting back around here, tape everything up that way that plug is still back there, and we'll have all these wires protected in the end.Once you get that plug all taped down, the next thing we're gonna do is take this wiring harness. We're gonna use the provided zip ties they'll give us. We're gonna zip tie it to the valve cover. So the next thing we're gonna do is take our water pump harness that they give us, we're gonna go on injector for number two cylinder which is on the driver side front. We're gonna plug this into the injector, and I'm gonna plug the injector harness into this other plug. After that, we're gonna run this section all the way down our radiator on the driver side. So to make sure that clips, we're gonna push the red lock down, then we're gonna plug this other side back into the injector, making sure that that clips, and then lock-in that red locking tab. After that, we're just gonna pick a safe route to take this down underneath to our radiator.So the next thing we need to do since this is an automatic transmission, we need to take our transmission fuel tube out. This is so we can cut it, spin a section around, and put it back together. So there's a few bolts down underneath of the Jeep, where it attaches to the transmission. Now, if you have a manual transmission, you don't need to do this. Why? Because you don't have a fuel tube. So underneath of the Jeep, on the side of the transmission, you're gonna have this bolt here. I'm gonna use a 10-millimeter socket to take that bolt up, so you can take the fuel tube out. So after that, we're gonna follow this fuel tube up. You're gonna see another bracket up here. That's gonna have another bolt in it. We're gonna use a 10-millimeter socket to get that bolt out. That should allow us to get the fuel tube out. After that, you can wiggle a dipstick tube and get it out of the Jeep. Now, we have the dipstick tube out. The next thing, we wanna do, we have to make a cut. So you wanna pull the dipstick all the way out.We're gonna measure down from this edge here about 135 millimeters, which for those of you that don't know anything about millimeters, it's about 5.3 inches. After we make that mark, we're gonna put on our safety glasses. We're gonna cut this tube as straight as possible right across. I'm gonna use a cut-off wheel. I'm gonna show you how to do that right now. So, after you get this cut, you wanna clean all of these edges up, make sure that there's no metal inside of here.Once everything is clean and prep, what we're gonna do is we're gonna take this piece that we cut, we're gonna spin it 180 degrees. So you're gonna get this rubber hose kit with two clamps. And what we're gonna do is slide a hose clamp onto our rubber section, slide our rubber section on. Then we wanna slide this about halfway down. After that, we're gonna place our other clamp on there. Then we're gonna slide our top section in, 180 degrees. Once those are all the way in and they touch, we can tighten these up. Now that's done, we're gonna reinstall it in the Jeep.So the next thing we have to do is install our water pump bracket and our new water pump. This is gonna go behind the bumper where our OEM vacuum pump is. Now, if you have a stock bumper, you may be able to get away without removing it. But if you do have to remove it, it's just gonna be a couple of 18-millimeter nuts and a couple of pushpins. We have an aftermarket bumper with a winch, so there was no way that we were getting in here, so we remove that whole assembly. Now, this vacuum pump normally, is in this stock location, but this bracket has already been cut, and it's been relocated. So, with the kit, you're gonna use this front stud here. With this particular Jeep, we're gonna use this back start here, so we're gonna use a 10-millimeter socket to take this nut off, and we'll get this bracket installed. So we're gonna take that nut off. We're gonna install this bracket with this end facing down.Once you get this bracket installed, the next we're gonna do is install our water pump. So this is just gonna slide down on this bottom section, and this backend is just gonna sit underneath of it. After we get that in, we're gonna put this zip tie in. This zip tie is gonna hold it in place. So after we get this install, you got to zip tie on. The next thing we're gonna do is install intercooler hose A. So you're gonna have this bend side here. This side is gonna go up under this little support bar, so we're gonna fish that up through there, and then this end is gonna attach there. So we're gonna take one of these black band clamps that they give us, and we're gonna attach that onto the end.The next thing we're gonna do is plug our water pump in. So we're gonna take that water pump harness that we plugged in and dropped down earlier. We're gonna route this in a way that it's not gonna get caught on anything or burnt. And once you pick a good spot for that, we're gonna plug our water pump in. After that, we're gonna take our ground, then we're gonna stick it under that nut that we put on to hold that bracket in place. Now, we're gonna take this wire, and we're just gonna zip tie it. Next, we're gonna take intercooler hose C, we're gonna drop this straight edge down to the bottom and underneath the radiator. So you're gonna bring this hose underneath of the radiator, above the sway bar, we're gonna connect this to our other port for our water pump. So we're gonna take another black hose clamp and slide that onto our water pump and put that clamp in place. So, next, we're gonna take in intercooler hose B, and this is gonna go on the passenger side in-between the radiator and the power steering fluid reservoir. You're gonna have a rubber flap down here. We're gonna pass this hook part through.All right. So the next thing that we're gonna do is assemble our intercooler and our intercooler bracket. So we're gonna start with the top bracket first. You'll have these two tabs up here. What they're gonna do is they're gonna go in these two holes up in this rad support. So you're gonna have this nut plate. This nut plate is gonna go up through this frame, and then we're gonna set that behind these holes. And we're gonna place this up there, and we're gonna use the two small Allen-headed bolts that we get in our kit to attach this bracket to that. So we're just gonna finger-tighten those bolts for now till we get the bottom section installed and the intercooler installed. So the next thing we're gonna do is we're gonna tuck this line up behind here. So this long hose is gonna get zip tied back here, so we're gonna install our zip ties.After that, we're gonna mount the lower intercooler mounts, so you're gonna have these slots in both its bracket and in its frame. All the thing is gonna do is just click onto this area, so we wanna line those slots up make sure that we press it on and click it in place. After that, we're gonna install our little intercooler. But before we install that, you're gonna have this little plug that comes with the kit. We're gonna install that into there. Then we're gonna use a 6-millimeter Allen key to tighten that up. Then you wanna torque it to 12 Newton-meters. After that, we're gonna install this, so you have these two welded ports up here. We're gonna stick this end in first, and we're gonna slide it underneath of this top bracket. Once we get it underneath of there, we're gonna take our M8 bolts, the flat washers that they give us, and we're gonna put them through these top holes.Once you get these bolts installed, we're gonna take a 13-millimeter wrench and tighten those up. So then we can go back up to the top, we can tighten these Allen head bolts. We're gonna use a 5-millimeter Allen key to tighten those up. So, this point in time, we can hook these hoses up to our intercooler. So we're gonna take two more black band clamps, and we're gonna do this upper hose and then the bottom hose. So, make sure that these hoses go all the way on and bottom out. So the next thing we're gonna do is take these little black studs that they give us in our hardware pack, and we're gonna insert them into this lower intake manifold. So we're gonna thread these in, making sure not to drop them down our ports. You can always stick some paper towel or tissue paper in there if you wanna cover them up. We're gonna take all seven of these and insert them in there. And then we're gonna take a 4-millimeter socket, we're gonna tighten these down and torque them.So these four studs, you want them on the inboard location. After that, we're gonna use that 4-millimeter socket to torque these to 8 Newton-meters. So, this point in time, we are ready to install the supercharger. So the first thing we're gonna do is take our supercharger, flip it upside down on a table because we have to take this bottom plate off. Bottom plate is held on with these four black bolts. But you can't get them free with your hand, you can use the 10-millimeter socket to get these out. What we have to do is we have to flip this plate over, then we're gonna reinstall these bolts. We're gonna capture them with some nylon lock nuts. After that, we're ready to install the plate on our Jeep. So, I'm gonna show you how to do that right now.So we're going to install these bolts up through the bottom, and then we're gonna take these little nyloc nuts that they give us, and we're just gonna capture them. So we just wanna do this finger-tight. And that way, it'll hold that bolt in there for when we place it on the engine. Now, we're ready to install it on the Jeep. But before we get this plate install, we're just gonna clean up some of this wiring in here. So like this harness here, we're gonna zip tied down to this valve cover. We can put our fuel line back on and then get on this stuff tuck down nice and neat, so we can get this plate on. After you get the plate on, the next thing we wanna do is take our nylon lock nuts both that we installed to hold these black bolts in, and the other three that come with the kit, and we're gonna install those on these studs. Make sure you don't drop any of these down the intake port.So what I did was I just stuck tape on the backside of these bolts just to hold them in because, of course, we're taking these nuts off. After that, we're gonna take a 10-millimeter socket, and we're just gonna tighten these down, making sure that we keep everything pretty even. But for right now, we just want to tighten this down, make sure that it's not crushing any wiring and make sure this thing is gonna sit all the way. All right. So once we have all these nuts installed, and we have them tighten down, the next thing we wanna do is torque them. So we're gonna torque them to 12 Newton-meters and make sure that everything is good to go. And then we'll move on to the next step. So one thing I'd like to point out is after you torque this, you may wanna let it sit for a while and then recheck the torque because we did have to torque them again. However, we're gonna move on to the next step.So the next step, we're gonna install our throttle body extension harness, and we're gonna install our map sensor extension harness. So that's gonna be these two plugs over on the driver side. We're gonna start with our map sensor. We're just gonna plug that end in. This harness is only gonna fit one plug, so we're gonna send this across the motor to the passenger side. Then we're gonna do the same thing for our throttle body. And then we'll make sure that both of them click. I'm gonna keep this over in this direction. So before we get our supercharger install, we're gonna do one thing. That's to install our pulley. Now, in the kit, you're gonna have two different thickness shims. We're gonna use our 1-millimeter shim. So you're gonna have a cut out in the back of this. The shim is gonna drop down in there. And then we're gonna use these four silver bolts that have an Allen head to attach that to our drive.After we do that, we're gonna torque it down. So I'm gonna show you how to do it right now. Once you get all these install, the next thing you have to do is torque them down, so we're gonna use a 5-millimeter Allen key. We're gonna hold this thing still. We're gonna torque it down with our torque wrench to 12 Newton-meters. So the way I'm holding the still is I'm just sticking a flathead screwdriver underneath, in-between these two bolt heads. In that way, we can attempt to hold this thing in place. So the last thing we have to do before we actually set this down on the motor is we need to install a bolt in the back of this intake. It's because it's a very long bolt. We're not gonna be able to get it in there when it sat on top of the motor.So in the upper intake manifold supercharger kit, you're gonna have a bag of hardware. You're gonna have two long bolts. We need to use the one that is 90 millimeters long, which is right around 3.5 inches. So you're gonna use the shorter of the long bolts, and you're gonna have a very thick washer that we're gonna place on that. So we're just gonna drop that in this hole, right in the back, and then we'll sit this on top of the motor. The last thing on the motor before we actually sat the supercharger down, we need to remove number six coil. This is gonna be the driver side rear coil pack, so we need is a 10-millimeter socket to get this bolt out. Then we need to unplug the coil, of course. So you need to press in on this little tab right here, and that's gonna allow you to disconnect that. And we can just wiggle, pull our coil out. So, at this point in time, we are ready to install our supercharger. So, now, what we're gonna do is carefully lower this down and place it on top of our lower manifold plate.Once you get the supercharger on and in place, the next thing we want to do is just catch a few threads with that bolt that we previously installed. I actually had to cut a little bit of insulation away just so we could get to that bolt and fit this thing in. Well, now, we're not gonna tighten that bolt up. The next thing we're gonna do is we're gonna install the longest bolt that they give us. We're gonna place another thick washer on that, and that's gonna go in this hole in the middle of the back. So we're gonna get that started with a few threads, and then we'll get some of the other hardware in. So, at this point in time, we still have to install those four black bolts that we had captured in the bottom of the intake. But we're gonna go around and use these silver bolts that have a flange head. So we're just gonna go around the perimeter and get all of these started by hand.So, right here in the front, we're gonna have one of those black bolts, so we need to get that started up into the intake manifold. We're gonna move on to this other hole, start that with one of those silver bolts. So underneath of our supercharger pulley next to our fuel line, you're gonna have another space for one of those black bolts. So we're gonna go ahead and get that one started by hand. We're gonna go down the driver side with those silver bolts, get all those installed. For the next thing we're gonna do is go around to the backside where we'll pull that coil out. We need to get those two black bolts in, so we're gonna get them hand-tight. Then we'll go around and torque everything down. So these last two bolts back here are pretty tricky to get in. They might take you a little while. So we finally get those in, so we're gonna go around and tighten everything up.So we're to start with these two back bolts underneath the rear of the supercharger. We're gonna use a 10-millimeter wrench to tighten these up. These back ones are very hard to get to, so you're gonna need to be very patient with them. We're supposed to torque them to 12 Newton-meters. So the third one we're gonna tighten is this one underneath of the decal. Same thing, you're gonna use a 10-millimeter, tighten that bad boy up. After you do that back one all the way back there, we're gonna do this one in the middle of the supercharger. So we're gonna torque that down to 12 Newton-meters. So we have one bolt left over. It turns out that this bolt goes back here, underneath of this pressure relief valve. So we're gonna install that now. That's the next one that we need to torque. So now, we have that bolt in and tightened up.The next thing we're gonna do is torque it down, so you're gonna need 1/4-inch drive, 10 swivel socket with an extension, just to get in behind here. So I have to get that one tight back there. We're gonna do these two right here. Same thing, we're gonna torque them to 12 Newton meters. So, next, we're gonna move over to the driver side, and we're gonna do these back two right here. Next, we're gonna go back over the passenger side. We're gonna do this one here. Next, we're gonna go back to the driver side. We're gonna do these two front ones here. So next, we're gonna go to the front of the motor. We're gonna do these for all across the front, so we're gonna start with this one right here. Next, we're gonna do this black-headed bolt right here, from underneath. Next, we're gonna do this one right here behind the oil filter housing. Then we're gonna do that last one underneath of there.The next thing we wanna do is gonna go to the driver side, and we're gonna put that coil back in that we took out. So you're just gonna press that back in, plug it back in. Then we're gonna reinstall that bolt, tighten it up with a 10-millimeter. Next thing we are gonna to do with this install is attached our idler pulley supercharger support bracket. This bracket is gonna attach to the front end, and this end is going to wrap around the supercharger. We're gonna have a little hole back here that this little foot is gonna sit in. It's actually gonna press up against the fuel line, so we need to kind of move that fuel line just a little bit out of the way. After that, we're gonna attach this band up here, so you're gonna have the strap. It's gonna go around there. And you're gonna take your M6 by 20-millimeter bolts which are the long hex head black bolts that they give you, and these are gonna screw into that. So we're gonna do that first, then we'll move on. We'll go ahead and get this other side installed.So next, we're gonna take our M6 by 12-millimeter bolts, and we're gonna install two down here. We're gonna take our last M6 by 12-millimeter bolt, and we're gonna place that flat washer that they give us in the kit. Now, this is the thinner of the flat washers, and you're gonna have two larger ones, therefore, the idler will pull this. This is gonna keep this from pulling through. So we're gonna install it on the backside of this bracket. Then once we get that hand-tight, we're gonna go around and torque all these down. So we're gonna go around and torque all these to 12 Newton-meters. Since we can't fit a socket torque wrench on this, we're just gonna use a wrench for that one. So we're gonna start with this one back here, tighten that one down. Then we're gonna do these two down here at the bottom. Since we can't use the torque wrench, we're gonna torque them down.So next, we're gonna do these top ones for the strap. Same thing, these are gonna get torqued to 12 Newton-meters. So now that we have this bracket on and secure, the next thing we're gonna do is install our idler pulleys. And these are reverse bolts, so you can put them on either way. After that, we're gonna use a large 3-millimeter thick flat washer that comes in our kit. We're gonna use the M8 by 16-millimeter long bolts. We're gonna install the bolt through the washer, and that's gonna attach it to the bracket. So we're gonna do that for both of these pulleys, and then we'll get them torqued down. So next, we're gonna grab our torque wrench with a 13-millimeter socket, we're gonna set it to 23 Newton-meters and torque these down.So next thing we're gonna do is install our alternator. And we already have our belt in, so we're gonna make sure that this stays somewhat out of the way. Then we get our alternator in the middle of that. Gonna place our alternator back down in here, making sure that this belt goes around it, and then we'll get our factory bolts reinstalled. So we can get those long shish kebab bolts in the top, and we're gonna install these other little guys down at the bottom. Once you get all that hardware installed, we're gonna go in, torque everything down. So these top larger longer bolts, we're gonna use a 15-millimeter socket. We're gonna torque them to 54 Newton-meters. So the bottom one, we're gonna use a 13-millimeter socket, and we're gonna torque that to 30 Newton-meters. And we'll do the same thing on the other side. So the next thing we're gonna do is plug our alternator in, so we're gonna click that, plug back on, and press that red lock-in. We're gonna put our terminal or wire back on our terminal, put that nut back on. Then we're gonna use a 13-millimeter socket, we're gonna torque that down to 13 Newton-meters. Then we can put our cover back on.So, this point in time, we are ready to install our belt and get it around these pulleys. So what we're gonna do is we're gonna take our 1/2-inch drive breaker bar, we're gonna go into our tensioner, making sure to push it in that little square. So we'll go in-between these two idler pulleys and around the supercharger pulley and make sure that the belt is on all of the other pulleys and accessories, and then you can release that tension, and now, our belt is on.So the next thing, we're gonna do is remove our stock throttle body from our stock intake just because we're gonna switch over to the new one. So you're gonna have four bolts in here. We're gonna need a 8-millimeter socket to get all those out. Then, we get it installed on the new one. And since we're swapping over our O-ring, we're gonna take this out without damaging it. So prior to installing the throttle body, we're gonna install that O-ring that we removed. So we're gonna fit this into the housing. Next thing, we're gonna install our throttle body. So you're gonna have four M6 by 40-millimeter Allen head bolts. Each one is going to get a washer, and we're gonna bolt this thing on. We're gonna use our 5-millimeter Allen key to get these things started, and then we'll tighten them up. Once we get it tighten them up, we just wanna make sure that we tighten them in a even way. It doesn't really tell us the torque spec in the instructions, so we're just gonna get these nice and tight, but we don't wanna over tighten them. After that, we're gonna plug our throttle body in.So the next thing we're gonna do is install our map sensor. That's gonna go right here in-between the intake and the supercharger. You're gonna get a brand-new one with this kit, and we're gonna lube this O-ring up just a little bit. After that, we're gonna go ahead and wiggle this in. Now, you're gonna get a self-tapping screw with this kit, so that's gonna go in that hole. We're gonna tighten that up using a 7-millimeter socket. Now, this screw is going into plastic, so we don't wanna tighten it too much because we might strip the plastic. So we just wanna get it pretty tight, and then we're gonna plug that in. We're gonna take this plug with the orange little rubber on there, we're gonna plug that in. We'll plug that in until that clicks. So the next thing we wanna do is zip ties some of this excess wiring up. That way, we can keep it away from our drive build.So the next thing we're gonna do is attach this engine breather hose onto this fitting back here. Next, we're gonna attach our intercooler lines. So this longer line that is coming from the driver side, that is gonna go to the back. So we're gonna install that one right there. So next, we're gonna come over to our passenger side, to our EVAP purge solenoid, and we're gonna remove this lower line. So you're gonna have this blue lock, we need to get that off. Then you're gonna press this white tab on the backside, that's gonna unlock that when you pull that line off. I'm just gonna use a little flathead screwdriver to get that lock off of there, and we can press in on the back. That's gonna free it up and allow us to slide it off. You're just gonna follow this line. We need to remove it from the vehicle, so we're gonna get it out of this little holding area. And then we're gonna move over to this bracket right here.So this bracket, we're gonna need to open this up. So we're gonna come down to the bottom and try to pry this open. We need a flathead screwdriver. So once you get that released, we're gonna try to get this thing out of the vehicle. So the next thing we're gonna do is install our new hose assembly. We're gonna click this onto our EVAP purge solenoid, and then we're gonna press that little blue locking tab in, and then we're gonna put this other side into our intake manifold. So, in this point in time, we're ready to install our factory airbox. We switch out our cold air intake for a stock one, so you're gonna have these three feet on the bottom. Those are gonna go. It needs rubber bushings down. So we're just gonna sit this over top and then press it in place. So now, we're ready to install our brand-new intake tube. Now, you have to switch over your map sensor, your mass airflow sensor.So what you're gonna do is pull that out of your stock intake. You're gonna grab this gently with pliers, turn it counterclockwise, wiggle it out, install it in here, turn it clockwise. After you do that, we're gonna put a band clamp on both ends. So we're gonna take our new air intake tube, and we'll install our brand-new band clamps that they give us. We're gonna start the throttle body side first. We're gonna make sure that that sits flush. Once we get it flush, we can tighten this up with a flathead screwdriver. Now, we're gonna connect this to our airbox. After that, we're gonna take our PCV hose, we're gonna attach it to this fitting on the airbox. After that, we are gonna plug in our massive flow sensors. You know, this little plug down here needs to connect to that little sensor. So make sure you go over to the driver side, and we're gonna install our brake booster vacuum hose. So this is gonna go on this port right here. I'm just gonna slide that on. That's gonna complete the installation of that hose.So, at this point in time, we are basically, done with the install in the engine bay. So the next thing you need to do is just go around and zip tie everything out of the way. So we have this new harness that we installed, we wanna bundle that up, zip tie that away from any hot and moving parts, especially the serpentine belt. The new heater core lines that we put in, we wanna zip tie those to this radiator hose here, and then just clean everything up and kinda keep it out of the way. So the next thing, we're gonna do is we're gonna fill up our supercharger's coolant system. So you're gonna have this cap right here, we're gonna twist that off. And we wanna stick our funnel in and fill it up with coolant. So we're gonna take our gallon of antifreeze, and we're gonna start filling the system up.We're gonna do it nice and slow because this is gonna purge some air bubbles out, and we don't wanna it just spill everywhere. The system is gonna take about 1.9 liters according to Sprintex. That's gonna be about half a gallon of coolant. So we got this system for the supercharger pretty much filled, so we're gonna put this cap on. After we run it, we will shut it down, check this level again, and top it off if need be. So we're gonna put this cap back on, and then we're gonna move to filling up our coolant system for the engine. So like I said the next thing that we are doing is adding coolant to the cooling system. This is the cooling system for the actual engine. Now, what we're using here is a vacuum system. This is gonna pull a vacuum on there, get all the air out of the system, and then we're gonna fill it with coolant. You don't have to necessarily use this, but this is what Sprintex wants you to use.So what we're gonna do is just install this down in there, and there we're gonna tighten up this lower section. It's gonna create a nice tight seal. And then we're gonna hook up our air line to that and cooler factory. And we're gonna make sure that it holds that vacuum before we fill it with coolant. So after we hook this air line up, we're gonna press this little button underneath of here, and that's gonna pull a vacuum. So if you are doing it this way with the system, you wanna pull a vacuum, at least, into the green. You wanna make sure that that vacuum holds. That way, we don't have any leaks in the system. After that, we're gonna hook up our other side, and we're gonna put that in our coolant bottle. After we do that, we're gonna open this valve just a little bit, so we can bleed all this air out. Then we're gonna pull another vacuum to get rid of all that air, then we'll suck our coolant in.So I'm gonna open this valve very slowly, and that's gonna suck all...It's gonna feel that whole line up with coolant. After that, we're gonna pull another quick vacuum. We wanna get that back into the green, and then we're gonna open this up and allow our system to fill up with coolant. While you're doing this, you wanna go very slowly. And we wanna make sure that we don't run out of coolant in the bottle, either. So it looks like we're good, so we're gonna disconnect this whole system. That's gonna give us a good head start on filling this cooling system up. So we had this clamp pinching off our overflow because that was actually keeping us from pulling a vacuum. So we're gonna take that off, and then we're just gonna top the system off. So what I'm doing is just squeezing the upper rad hose, and that's gonna allow us to burp some of those extra bubbles out, pretty much wanna do that until there's no more bubbles left.So we're gonna go over to our coolant overflow. We're gonna open that up and just fill that up a little bit since ours is slightly empty. In that way, when we run the engine, if it needs to suck a little bit more in, it can pull from this. It's about halfway. It should be good. Reinstall our radiator cap. Next, we're gonna reconnect our battery's negative terminal. Then we're gonna use a 10-millimeter socket to tighten up that nut. So, at this point in time, we are ready to load our tune. So inside of the Jeep with the tuner, most likely, when you get this thing, it's gonna need an update. Now, you can do this via Wi-Fi if you have that available, or you can plug it into your computer, go to DiabloSport website, and then update the tuner as well. So we've already updated our tuner. What we're gonna do is take our OBD2 cable, we're gonna plug that into our tuner.Then we're gonna plug this other end into our OBD2 port. This is underneath the dash near your left leg. So once you plug it in, this is gonna power up. So we're gonna stick our key in the ignition and wait for this thing to turn on. So it's gonna ask us to agree to the terms. We're gonna press Yes. Then we're gonna click tune the vehicle. After that, we're gonna make sure that the key is in the Run position. So you don't wanna start the engine. You just wanna turn the key to the Run position. After that, we're gonna press Continue. Then we're gonna click Yes. So what this tuner is gonna do right now is it's gonna save our stock tune, and then it's gonna upload the new tune. So right now, it is pulling the stock tune. "Please turn your ignition off," so we're gonna turn that off. Then we're gonna press Continue. Now, it's asking us to turn the engine back on or the ignition on. We don't wanna start the engine, gonna press Continue.So now, we just have to wait for this to load 100%, and then hopefully, our tune is installed, and we can fire this thing up. All right. So it's done loading. It's asking us to turn the ignition off, so we're gonna do that, press Okay. Now, it's asking for the ignition on, still not starting the vehicle. Pressing Continue. All right. And it looks like we are complete, so we're gonna continue, and then we can unplug the tool. So, at this point in time, we should be okay to unplug the tuner, so we're just gonna turn the engine off, unplug the tuner. So, at this point in time, we are just gonna start this Jeep up. So we started our Jeep up, and we allowed it to run for a little while. This is so it can burp out all of the air in both of the cooling systems. After that, we shut it down. We check for leaks, and we also open those up and top them off.Now, the supercharger is encase and filled with oil, but there is a dipstick on top. You can pull that out and make sure that it has the correct level. So, this point in time, you should be all good to go, so you're ready to reinstall the grille. And if you did take your bumper off, you can put that back on. So next, what we're gonna do is reinstall our grille. So we'll need to click those lights back in that we took out. This is gonna be the reverse order of exactly how we took it apart. After that, we're gonna click our bottom in, so we're gonna line that up, click our bottom in. We're gonna install our top pushpins. So we've finally got the supercharger installed. What we're doing is taking it for a test drive right now. We're gonna drive it around for a little while. Let it warm up, kinda get a feel for it or dive a little deeper in it and know exactly what's going on here.So driving this thing moderately is very smooth, you don't really hear the supercharger a lot. But just driving it around like a Jeep, I mean, you could totally daily drive this thing. And you'd never even know it was there until you give it some throttle. So if I can hear it inside of the Jeep, people are definitely gonna be able to hear it outside of the Jeep. So everyone is gonna know that your Jeep is supercharged. They're gonna know that it's a lot cooler than their Jeep. So a lot of time when we're off-roading, we get into situations where we get stuck. If you have larger tires and you're in a sticky situation and your motor just isn't cutting it, having a supercharger give you an extra 100 horses. It's gonna allow you to throttle your way out of a situation. So driving on the highway, highway speed doing 60 miles an hour right now, I don't really hear the supercharger whining at all. It has a pretty smooth idle.There's no real fluctuation or anything like that. So far, we haven't gone above operating temperature. We kept a nice cool temperature. This supercharger has its own water-to-air intercooler which so far has been really good. So we're running really nice. It's a very smooth idle. This whole system is designed to build boost at a very low RPM, which is gonna be great for highway driving. It's gonna be great for off-roading. It's gonna give you a lot a low-end torque, which these larger vehicles need. So we add a lot of weight to these jeeps. They're already heavy to begin with, especially the four-door model. So bumping up that power and giving it greater acceleration is gonna make your drive more enjoyable.I'll tell you what? This is gonna make your Jeep a lot more fun to drive. You're looking to add a ton of power to your Jeep, a ton of pickup, throttle response, a really cool supercharger sound. And honestly, just having a lot more fun, enjoying driving your Jeep around, even more than you already do because it's a Jeep. We all have fun driving our Jeeps. I think this is a great option to go with. It's really gonna be nice. So you're really gonna be happy with it. For more videos like this, check us out at extremeterrain.com.

Hardware good! Tuning is terrible!
So this is going to be a long review and I’d like to start off with saying that I do like this supercharger. I’m going to answer some questions that I had before purchasing and give my recommendations based on my experience. This is a lengthy install but the only difficulties are getting in the tight places when bolting down the blower...I mean really tight places! You will need someone with tiny hands. Follow the instructions on Sprintex website, not the video on here because some steps are left out. Before you even purchase this or any supercharger kit, you need to research who can do custom tuning for you. IT WILL NEED TO BE CUSTOM TUNED!!! When I finished the install, it took 5 days for Sprintex and Diablo to get the tuner to work and a tune just to be able to drive it around. Sprintex and Diablo were back and forth on who’s fought it was and the Sprintex guy even said it was my Jeep that was the problem. Then after I called him out on it, he said now they has another Jeep with the same issues and someone in Indonesia or somewhere could write a custom tune for it. After a month I found a guy in south ga that can custom tune. After that, it was amazing. On the dyno mine pulled 282 RWHP with 37” tires and 4:56 gears. I told the tuning guy that I wanted to play it safe or he probably could’ve gotten more HP out of it. I wanted more drive ability. If you have concerns about the loudness of the blower when driving, it’s not bad at all. When driving down the road with the radio on, you can’t hear it unless you get on it. I bought the stage one kit because mine was an older Jeep with 140,000 miles on the engine. If you have a new or newer Jeep, I would recommend spending the extra money on the stage 2. Again, I recommend finding someone who can custom tune before even purchasing this or any kit. When reading other reviews along with my experience, this was the biggest issues. Expect your fuel mileage to drop also. Again, since I had it custom tuned, I’ve been very happy with the power I have and the increased drive ability.Helpful (7)

Meh, don't waste your time
The hardware is okay. But, there are issues getting to plugs after installed due to design flaw. Most of the time the plate needs to be removed which is a PITA. Sometimes they call you back and sometimes not. Their stock tune has the worst fueling I have ever seen. Required divine intervention to get it to stop dumping fuel on startup as it runs very rich and will trigger banks A/B. Also, you will need a custom tuned TCM and stock won't cut it. Budget for those things and a pro install to ensure reliability.Helpful (18)

Breaks the tires loose in second gear, what more do you need? This has great throttle response and even better power. I live in salt lake and have frequent trips to park city and it’s a climb this gets me there quick and in 6th gear the whole time no down shifting and no lag great quality and easy to installHelpful (17)

amazing product gives out unbelievable amount of hp and torque looks and sounds sick gives amazing milage with this product installed i went from getting 10 mpg to 14mpg after i installed this product i recommend this product to everyoneHelpful (30)
Will this product fit a Jeep with a manual transmission?
The Sprintex 3.6L CUR Intercooled Supercharger System with Tuner (12-17 Wrangler JK) should work with 2012-2017 Wrangler JK's with both Automatic and Manual transmissions.
How much hp gain?
Hello, as per Sprintex, this Supercharger will give you 54% more horsepower; 195 WHP stock to 302 WHP supercharged and 28% more torque; 239 lb/ft stock to 307 lb/ft supercharged.
I have a traildash 2 do I need any other tuner
The TrailDash2 is not designed to work with supercharged or forced induction Wranglers so you will need a different tuner. The Sprintex 3.6L CUR Intercooled Supercharger System with Tuner (12-16 Wrangler JK) does include a tuner for use with your Wrangler.
I find this an interesting option. Since it’s low boost does it still allow you to run the standard 87 octane or do you need to go up to 91 ?
Can you reach the oil filter without disassembling parts of the super charger kit? It looks like the throttle body and intake cover access.
This is a complete kit for stock applications. 2015 and 2016 JK's will requireto purchase a modified PCM from DiabloSport. You would need to provide DiabloSport your VIN number and mileage when purchasing the modified PCM. Please contact DiabloSport through //www.diablosport.com/contact/
This would come with its own flash tuner. with a preloaded tune that will be used in conjunction with the supercharger.
