      Video Review & Installation

      Hey guys, I'm Eric with ExtremeTerrain. In this video, we're gonna show you a review and install of this K&N Series 63 AirCharger Cold Air Intake for all 2020 and later Jeep Gladiators with the 3.6-liter V6. Now, this kit's really gonna appeal to the Gladiator owner out there who is looking for a little bit of a boost in power and much better throttle response from their Jeep, and they wanna use a top name brand to get it. Now, as you'll see in this video, the design and layout of this cold air intake is not a whole lot different than your factory intake, but really what's at the heart of all the gains in power and throttle response is that premium air filter that comes with this K&N cold air intake. Now, this premium air filter from K&N is really gonna let in a lot more air compared to a factory air filter, but it's also gonna keep out the same contaminants, dust, and dirt that you wanna keep outta your engine. Another advantage to this air filter is that it's reusable.So when it gets all dirtied up, all you need to do is remove it, clean it, reoil it, and reinstall it. And it's gonna have a long service life. In fact, K&N has an industry-leading 10-year million-mile warranty that they use to back up this cold air intake. Now they're confident with that warranty specifically because they use heavy-duty quality materials in the construction of all of their products, which includes this cold air intake. Currently, this unit is priced at around $375 and considering the upgrade in performance, durability, and long lifespan, I think that's really a reasonable price. You would be looking at spending just as much on other lesser brands and sometimes even more money than what you're paying for this K&N kit. With all that said, at the time that we made this video, this kit is not CARB-certified. Meaning that any states that use California's emission standards, this will not be legal to operate in those states.But with that said, the installation is very easy bolt-up. I'm gonna show you how to do that in just a second. We're giving it a very basic one out of three wrenches on our difficulty meter. I would say budget about one hour of your time, you should have this kit installed. No problem. No exotic tools, just some basic ones out of your kit. We'll show you what you're gonna need here in just a second. So let's go ahead with the installation. Okay. The tools we're gonna use for this install include an electric impact wrench, a socket wrench, a socket extension, a 4-millimeter Allen socket, T20 and T30 Torx bits, an 8-millimeter and 10-millimeter socket, a pair of pliers, a 19-millimeter crescent wrench, and a trim removal tool.All right, guys, now to get us started, you should disconnect your battery with the negative terminal. That's recommended from the manufacturer of this. And anytime you're doing anything under the hood, it's not a bad idea to cut off the electrical supply to the engine compartment. So what we're gonna do first, we're gonna pop a couple of clips, loosen a few bolt, and we'll get our factory airbox and intake out of the Jeep. All right, guys, go ahead and disconnect the sensor wiring harness, just pinch and pull. And if you have a flat-head screwdriver or a trim removal tool, something like this, just pop this clip out here. And same thing for this one. Just kind of cut that out of the way. All right. Now we're gonna pull this one out. Because these are all attached to our factory intake, which obviously we're gonna remove.All right, guys, now we're gonna remove these two bolts here using a 10-millimeter socket. All right, guys, now we're gonna loosen the clamp here that attaches our intake to our throttle body, and an 8-millimeter socket is what you need for this. All right, guys, now we're gonna remove this bolt. Again, 10-millimeter socket. All right, guys, now we have to disconnect our rebreather CCV pipe from the intake. This is kind of pinches. All right, guys, with all that disconnected, now we should be able to pull the airbox up and pull the intake off the throttle body. All right, guys, now that we have our intake and airbox out, I wanted to point something out to you as a little tip when you're removing this. When you pull your airbox out where you're looking at the bottom of it right now, there are these two posts. And when they push down into the Jeep, they go into these rubber grommets. And we wanna reuse those for our install of our new airbox. So basically, it should look like this. You don't want the rubber to come out with your factory airbox. So pull it off. Because when I pulled this out, this came with it, so I'm gonna show you where to put this back into place so we can reuse it.All right, guys, so what you're looking at is where those posts go in. As you can see, there's a rubber grommet that's stayed in place. I'm gonna take the one I just pulled off the airbox and I'm just gonna re-seat it back in that hole there so we can reuse it. All right, guys, next we need to remove our grille. There is another piece of ductwork behind the grille here that we're gonna have to remove. So in order to do that, go ahead and grab a trim removal tool if you have one or a flat-head screwdriver because we're gonna remove the locking clips across the top of the grille. All right, guys, now we have six of these locking clips that we're gonna remove across the top. If you've never worked with these before, they're two pieces. The center post is kind of a locking pin. You wanna pull that up first like that and then get underneath the base of it. And then that pops right out, just like that. So we have five more to do.All right, guys, now that we have those top locking clips out. There's just a row of pinch clips along the bottom here. So you wanna grab the bottom of the grille and just kind of give it a little yank and pull it out and that's it. All right, guys, now we're gonna remove this support bar right here so we can get access to these two bolts. For these bolts here, you're gonna need a T30 Torx bit. All right. Now for these two bolts, you're gonna need a T20 Torx bit. All right. Now go ahead and remove this ductwork. And we're pulling this ductwork out, there's a little post right here, guys, that seats in a grommet. So just kind of pull up on that and then this comes right out. All right, guys, now we can reinstall our support rad here. Again, you're gonna want a T30 Torx bit for this.All right, guys, now that we have our factory intake out of our Jeep, I wanted to throw up here in the table and do a real quick side-by-side comparison. There's not a whole lot to see here. We're trading out kind of dirty, worn out, a little bit faded factory original plastic for some brand new stuff from K&N. Now obviously, this is a little bit thicker material, a lot more durable. I think it's gonna withstand the engine compartment heat a lot better than your factory stuff, but really what's at the heart of this new K&N cold air intake is their high-performance filters. It's gonna let a lot of more air in while still being able to keep out the contaminants like dust and dirt and other types of particles that you don't wanna get into your engine. And also, this is a reusable cleanable filter. So, obviously, you're gonna be saving money down the road. Another nice advantage to this cold air intake.So let's go ahead, do some table assembly work here, and then we'll get it mounted on our Gladiator. All right, guys, one thing we need from our factory intake before we can cast it aside is we're gonna remove the intake air temperature sensor. It's a little tight and we're gonna mount this on our new K&N intake. All right, guys, on our new intake tube from K&N here, right at the elbow bend, there's this hole. Take this rubber grommet out of your new kit. Get it fit in there. All right. Once you get that grommet seated in there, go ahead and take your sensor and just kind of work it in there. Gonna be a little snug. And then check on the inside to make sure that the sensor is exposed. All right, guys, now go ahead and grab this piece. This is a connector for the crankcase valve rebreather hose. That started, and we need a 19-millimeter crescent to snug this up.Next, we need to mount these two posts that go on the underside of the airbox. And they're gonna push down into those rubber grommets that we talked about earlier. So go ahead and grab this hardware out of your kit. You're gonna need one of these hex head bolts, a lock washer, and a flat washer for each one. And the hardware is gonna go through the inside of the airbox and this will be on the outside. You're gonna wanna mount them up on these raised beveled edges or holes right here on the bottom of the airbox.And to tighten up those bolts, you can get a 10-millimeter socket or a wrench inside here to tighten them up. All right, guys, now we're gonna mount up the filter to the intake tube. Go ahead and grab the large clamp out of your kit, get it onto the filter. Slide it on nice and snug. And then to tighten the clamp down, you need an 8-millimeter socket. All right. We're gonna feed the filter into the airbox, just like this. And then go ahead and grab the three button-head Allen socket bolts out of your kit and a flat washer for each. And that's what we're gonna use to attach this duct to the airbox. We'll just get it started. And then to tighten them down, you're gonna need a 4-millimeter Allen socket or an Allen key.All right, guys, now we have to attach the coupler piece to here, and this is what's gonna connect our K&N intake to the throttle body for the truck. So go ahead and grab these two clamps out of the kit, get them started onto your connector piece. And you're gonna want to mount the other one on the opposite side with the bolts pointing up so you can access them with a tool. Now we're gonna move to the truck. All right, guys, now we're gonna drop the intake into place. These posts here, we're gonna wanna get down into the rubber grommets down below and kind of be mindful of your rebreather hose right here and lining it up to the throttle body as well. Kind of a lot going on at once, so we're just gonna take it slowly.All right. Now that that's down and in, we can take one of our factory bolts here, get this bolt started by hand, and you're gonna need a 10-mill socket to tighten it down. All right. Now we're gonna tighten the two clamps here at our coupler by the throttle body. These are 8 millimeters. All right. Reconnect the plug on your sensor. And then reconnect your breather hose. All right, guys, now go ahead and replace your grill. Remember you have that row of pinch clips at the bottom where you wanna line those up, and then push them into place. And then grab your lock pins and push those into place across the top.Okay, guys, that wraps up this review and install of this K&N Series 63 AirCharger Cold Air Intake for all 2020 and later Jeep Gladiators with the 3.6-liter V6. Now, of course, for all things Gladiator, keep it right here at
