      Review & Installation Video

      Hey, guys. So today I'm here with the Injen Power Flow Cold Air Intake with the oiled filter in wrinkle black, fitting all 2018 and newer JL Wranglers with that 3.6 liter V6 engine. So, if you've added larger wheels and tires to your Wrangler or you've added just a little bit of weight and you're noticing some sluggishness or lack of fuel efficiency, a cold air intake is a perfect way to gain some of that horsepower, torque, throttle response, and fuel efficiency back. So, this option by Injen is going to do all of that with a dyno gain of 9 horsepower and 11 foot pounds of torque. Now, since we are Jeep owners, we will see those gains in the higher RPMs where we don't spend a lot of time. However, what you're going to notice from this is that gain in throttle response as well as fuel efficiency. Now, this does have a closed box design, so I would recommend this to somebody who is on the East Coast, maybe in a wetter climate who wants to keep that filter inside a little more protected than an open box design with just that heat shield and the filter exposed. Now, if you are doing a little bit more water crossing than this would allow, I would recommend to take a look at some of our snorkel options on the page. But, I definitely think is gonna do a great job at keeping a lot of that water out and away from that filter. This is also gonna feature an oiled filter, which is going to be a little bit better as far as efficiency goes and air flow goes over a dried filter. However, it will require a little bit more maintenance, so that really comes down to personal preference on that one. But, this is gonna do a great job at filtration and getting all of that cold air in and to your throttle body. Now, it's also just gonna look a lot better than your factory intake system. You do get the Injen branding here with a little bit of a window to see that red filter inside. And it's overall gonna really look nice and a lot more attractive, a little bit more sportier than your factory system. Now, this is gonna be roughly $330, making this a very averagely priced cold air intake on the page. Now, other more expensive options, they're usually just going to have a little bit more of a gain as far as horsepower and torque numbers go. But, again we are Jeep owners. I personally think that if you're just looking for a little bit more efficiency, a little bit more throttle response, then something like this is definitely worth the money, especially if you're on a budget and you're not looking to spend everything on a cold air intake. I also like the fact that this is pretty simple. It's very well built. A lot of intakes that I've seen do require a lot of assembly right out of the box. This is a three-piece system. You're getting the filter, you're getting the airbox, and you're also getting the intake tube, making it very easy to install and a very simple process overall. So, speaking of that install, guys, this going to be a light two out of three wrenches on the difficulty meter. It is pretty easy to install. You're gonna need some basic hand tools and about an hour's worth of your time. So, speaking of that install, let's jump into that now.The tools that I used for my install were an impact wrench, a 10-millimeter and 8-millimeter deep socket, flathead screwdriver, and a trim removal tool. So, obviously our first step is gonna be to pop the hood. Then, we're gonna disconnect a couple of things that are connected to our intake before we fully remove it. So, I'm gonna take a trim removal tool and we're gonna remove a couple of clips that are holding on our IAT sensor wire on our resonator here. So, there's gonna be two tabs here and then a tab over here. Then, we can remove the sensor for our IAT sensor. This is your intake air temperature sensor. You can just depress that clip and pull it out. Now, we will be removing this in just a little bit and transferring it over to our new intake system, but we can keep that there as of right now, and we can move onto our PCV hose. So, all you have to do is just squeeze this and give it a good tug back. That's going to be attached to our new intake as well. Then, we can remove these two bolts up front that's actually holding our intake tube in place. I'm gonna take a 10-millimeter socket and go ahead and remove those. So next step is heading up to the throttle body clamp. I'm gonna take an 8-millimeter socket and go ahead and loosen up this clamp. You can also take a flathead screwdriver. As you can tell, there is a notch in there. An 8-millimeter socket works out a little bit better and a little bit quicker. Then, we can wiggle that off. So, after our intake is disconnected from our throttle body, it will be free enough to remove. However, we do need to remove this last bolt from our airbox. So, I'm gonna use that 10-millimeter socket again and then we'll be able to fully remove our intake. So, now we can pop our intake out of place and fully remove it.So, like I mentioned before, we do have to remove our IAT sensor and switch it over to our new intake system. So, all you really have to do is twist this off. I am going to use a flathead just to get this tab over this piece here. Go ahead and twist it. You do need to lift up on the tab to clear that, because that's gonna lock it in place. And then, once you have that over, you can twist and pull that out. So, before we can go ahead and install our intake on our Jeep, we do have to do a little bit of assembly. So first, we're gonna start off with that IAT sensor that we just removed out of our stock intake. Injen is gonna provide you with a grommet. So, we're gonna take our intake tube, and there's gonna be a little hole down at the bottom, and we're gonna go ahead and install that grommet in there so we can house our IAT sensor. So, you kind of have to manipulate the grommet to get it to sit flat. There is gonna be a slit right in the middle that you want to be on the actual edge of that intake tube. If you do need a little bit of help with this, you can use a flathead screwdriver kind of to get it seated. I would be careful though. You don't want the metal of the actual screwdriver tearing the grommet. But, once that is sitting pretty flush, we can grab our intake air temperature sensor and wiggle that in. You also wanna make sure that that tab that was seated on your stock intake is sitting seated on here as well. You wanna make sure it's sitting pretty flush. So, now we can put our cone filter into our intake box. You wanna make sure that Injen is facing forward as oriented in the Wrangler, and you will have two sides here. One is going to have the Injen logo, and then one will have a manufacturer part number imprinted in the airbox. You wanna make sure that that part number is facing forward also, that if you're staring at your engine bay, Injen is going to be facing you and not facing the other way. So, then we can put our cone filter in and have it sitting flush, and this is gonna have twist and lock technology. So, all you have to do is twist it a quarter turn and it'll be locked into place. As you can tell, I'm pulling up on it and it's not moving anywhere.So, after we have our filter in our intake box, our IAT sensor in our intake tube, we can put together our bracket. Now, this is going to hold our intake box in place. It's gonna be bolted down at the bottom of our intake here. And then, we're gonna take our standoff studs and those are going to be inserted in the OEM grommets that are in our engine bay already. So, we can grab our standoff studs and our flat wash washers and our flange nuts. We can go ahead and put that together. So, this is going to act as a cradle. We're going to install the standoff studs on the bottom here. So, we're just going to take that stud, take that flat washer and the flange nut, go ahead and screw that on. Then, we can go ahead and tighten them down with a 10-millimeter socket. Now, I have the clutch on one. They don't need to be tightened down super tight. You just wanna make sure that they're not gonna go anywhere.So, after we have our standoff studs in place, we can attach this bracket as more or less a cradle on the bottom of our intake box. Now, again if you're looking at the intake box from your engine bay, you wanna have this window up at the top with Injen facing you. So, if you're looking into the engine bay, you're going to be able to read this perfectly. So, we're gonna flip that up on its side. I also would like to mention since we are a little bit closer up, these two holes that are gonna be attached to our intake box are going to be offset. As you can tell, they're not level, and that's going to be perfectly okay. It's going to fit up perfectly to our intake box. So, you wanna make sure that your standoff studs are on the opposite side with the holes that line up. So, once you have them both threaded, we can tighten them down. I'm using a 10-millimeter socket again. Now, what we're gonna do next is connect all the pieces. So, we're going to take the larger flange to our cone filter here, making sure that the label is even with the top of our intake box. We can put that into place and we're gonna loosely install our clamp here. I'm using an 8-millimeter socket. So, then we can loosely install our coupler on the other side. This is going to connect our intake to our throttle body. So, I'm just tightening up the clamps just so they're not flopping around on us. You're gonna have two clamps. I'm just going to install this with the Injen facing in so we can read it from our engine bay. Doesn't really matter which way you install it. But, you wanna make sure that it's sitting over the intake tube when you tighten it down. Right now, we're not tightening anything down, but you do wanna make sure it's in position. Then, we can just throw our other clamp on, leave that a little bit loose. Don't want it flapping around on you. You can just tighten it up for the time being. Now, we're ready to install that on our Wrangler. So, before we go ahead and install our new intake system on our Wrangler, I did want to sit these side by side and show you guys a little bit of a comparison. Now, overall with the build, this is gonna be a pretty similar design to your stock intake system. Now, you are getting a closed box design. That's gonna provide a little bit of protection to your filter inside from any contaminants getting inside of your engine bay, especially water in those wetter climates. Now, you also are getting a one piece sealed housing with this or a one piece sealed box with this, in comparison to your factory system, where it is two pieces, and if you did have to replace that filter inside, you will have to actually separate the top and the bottom of your airbox in order to do that. With this, you do have a twist and lock feature as you guys saw when we were putting this together. All you have to do is put the filter inside, twist it a quarter turn, and it's locked in place, which I do really like. It makes it very easy for installation. Now, moving onto the intake tube, this is going to be a large aluminum intake tube, and in comparison to your factory one, you do have a resonator here that's gonna cause a little bit of restriction. So with this, you are streamlining that airflow from your filter all the way down to your throttle body, increasing that airflow.So, to break that down into simpler terms for you guys, this is going to offer all of that filtration a lot better than your stock media or your stock intake filter without all of that restriction. So, this is gonna have less restriction opening up all of that airflow for you. Now, this is also gonna be a dry filter. So, in comparison to your paper filter, that's also gonna be dry, but that is gonna require you to replace it after so many miles. With this, you do get to clean it. This is very easy to clean. All you have to do is take it, your filter out and clean it with a Shop-Vac or pressured air. Very easy to clean over an oiled filter. So, in comparison to an oiled filter, that is going to require a recharge kit. With this, you are completely eliminating all of that process, all of that extra process, and all you have to do is take some pressured air to it and it's completely clean. You can throw it back in and get back on the road. Now, this is also going to come with everything that you need to install it. You don't have to transfer anything over from your factory system. The only thing that you're gonna have to transfer over which you saw earlier, was your IAT sensor. But other than that, this is gonna come with a new silicone coupler and also some stainless steel clamps. So, speaking of install, let's go ahead and put this on our Wrangler.So, with the intake together and the clamps loosened up, we can put this into place. And we'll be able to position it over our throttle body. Might have to loosen up your clamps. We're gonna go ahead and tighten them back down. I'm using that 8-millimeter socket. That's really all you're gonna need for this. Then, we can move over to our factory box, push those standing studs down into those factory grommets down there. Make sure our intake tube is positioned in our filter correctly. Can move all of the clamps into position, making sure that they're easily accessible for if we ever have to take this off in the future. Also making sure that our clamps are over all of our tubes. So, you wanna make sure that your clamp is fitting over that throttle body lip as well as the lip on your intake tube and so on down to your filter. Then, we can take our 8-millimeter socket or you can use a flathead, since these clamps do have that groove as well and we can go ahead and tighten that up. Now you don't wanna make the actual silicone coupler bulge. You wanna make sure it's tight so there's no air leaks, but you don't want to tighten it down too much to where that silicone coupler is bulging. So, now we can move over to the filter side, tighten that down, making sure that that clamp is on the end of that lip there. It's gonna be with that same 8-millimeter socket. And then, we can move onto installing our hoses. So, our PCV hose, we can just give that a good push, should click into place. So, our last step is just to plug in that IAT sensor. You should hear it click into place. And then, you can just close up your hood and you're all set to go. So, that's gonna wrap it up for my review and install. Make sure you like and subscribe.

        Super easy install. It looks great, you can feel that there is no restriction on air flow, and it saves some space. I can’t hear a difference, but then again, I added the pypes high clearance exhaust a week earlier. Great product by a great company.
