Matt: Today on CJ Off Road we're gonna help our JL breathe a little easier with the help from Engine.

If you're looking to increase the performance of your JL Wrangler by adding on a simple cold air intake, today we're gonna be installing this Injen super nano web drive filter featuring the Power Flow polished tube onto our 2018 JL Wrangler. This Injen cold air intake includes everything that you need to get it bolted up to your 3.6 liter JL Wrangler. It features a T6 6061 mandrel bent induction tube that is in the polished finish to give it a nice classy look underneath the hood. As a super nano web drive filter which is going to increase performance, and according to Injen will increase your horsepower by nine, and foot pounds of torque by 11. It also features a black plastic intake surround, which is going to protect that drive filter from any mud or debris getting inside your intake. It includes all the necessarily hardware, and is also available in a black finish, as well as with an oil filter. That being said, let's get it installed in our 2018 JL Wrangler.

The tools you need for this installation, a 1/4 inch ratchet, 8mm socket, 10mm socket, trim removal tool, and a small pair of pliers.

We're at the front end of our JL and before we can install our new Engine cold air intake we're gonna remove the factory intake system. The first step of the removal process is to remove this breather hose right here by depressing on this gray section and pulling towards the firewall. Just pop right out.

Next remove the two 10mm bolts holding on this factory induction tube. To remove the temperature sensor here what we're going to do is just lightly twist it counter clockwise with an adjustable crescent wrench and pull it straight out. Just be very careful with these, they're plastic, don't put too much pressure on them or they will break. From the inside here just grab a hold of it. Twist it lightly counter clockwise, and you can do it by hand just breaking it free in the beginning, and then just slowly rock it back and forth, and it will pull right out. Remove the two pushpins holding it on here. Just set the sensor aside in a safe spot.

There's another push pin that actually holds onto your factory intake that you have to remove before you can get it out. It's right behind here. I've got the trim remover tool on it. Just pop it up. Up by the throttle body there's going to be an 8mm bolt that holds on this band clamp from the South part of your induction tube. Use an 8mm socket to get it pulled off, or you can use a flat head screw driver, don't fully twist it off, just enough to loosen it up so you can get this off your throttle body. The last bolt holding this intake on is going to be this 10mm here over on the passenger side fender. Once again, just pull that out. Once it's free we'll now be able to remove the entire intake. Now over here it's actually stuck in through these rubber grommets, give it a nice pull, just work on it a little bit, and it will pull right out. We've got our Injen intake box here, and our filter, and now what we're gonna do is actually interlock the filter into here before we start this install.

We can turn it around the this side, and now when you slide it in there's actually a little lump right here, or a little cut out, and you're gonna place that matching up with the one on the filter, and it will set in, and twist it clockwise about a 1/4 turn, it'll stop, and now that's completely locked into there. It won't move and it's a really secure way to have this on. Now this intake box has a small window here as you can look in and see how your filter's doing. We're gonna turn that so it faces upwards, and you're gonna have some markings. This is actually gonna face the front radiator support. And what we're gonna do is take this edge with the offset holes and set it like this right onto the intake box.

Use the provided hardware. And we can get this tightened up with a 10mm socket. With the box flipped upside down you're gonna put these included studs through the bottom hole going upwards, and put a washer and the flange nut onto there. Tighten it by hand. Then we use a ratchet to pull it tight. All right.

Now you're ready to install it into the Jeep. Place your intake box into place by pushing it into the factory location to the grommets, and it will freely stand a little bit, fall a tad bit, but we're gonna put that tube in as well as get some clamps up on this throttle body next. Slide two clamps over here, and then we're gonna put this right over the factory throttle body. Push it all the way to the edge. Make sure it goes underneath too. Hook the clamps to both edges. Now we can go get our intake tube. Place the grommet for the temperature sensor on your intake tube. Make sure it's fully seeded. We're gonna push this end of the intake tube onto the throttle body side. And then before we get in onto our air box, I'm actually gonna take one of these clamps and slip it over here. Rotate it downwards. Let's get these clamps tightened up using an 8mm socket. Then we get our temperature sensor installed. We're going to now reinstall the temperature sensor onto that grommet that you installed.

Just lightly twist as you go in that way the grommet doesn't fall inside the tube. There you go. It's fully seeded. Place this clip back onto place. Hear the snap. Then we can tighten down our last clamp over here on the air box. Once you get that last hose clamp tightened up, your installation's complete.

Well the Engine cold air intake is successfully installed into our 2018 JL Wrangler, and honestly it looks really awesome under our engine bay here. It classes it up in the front, it removed a lot of extra weight that we had up there with that big bulky factory air box. It took about an hour to remove it and install the new one, which I think is really simple for an intake kit. And you can find it as well as the black tube right here at I hope you enjoyed that video.
