If you're looking to get some more performance out of your Jeep JL, today we're gonna be installing this Injen power-flow cold-intake featuring the wrinkle black induction tube and an oiled filter onto our 2018 JL Wrangler.
This Injen cold-air intake includes everything you need to get it bolted up on your 3.6 liter equipped JL Wrangler. It features a T-6, 6661 mandrel-bend aluminum induction tube. It has a wrinkle black powder coat, and then that's topped off with our oiled cotton filter which is going to let air in, keep all the mud and water out. Everything that you need is included with this kit and it's also available with a polished induction tube and a dry filter. Now with that being said, we're gonna get it installed in our two door JL Wrangler and see how it performs.
Tools you need for this installation: quarter inch ratchet, 8 millimeter socket, 10 millimeter 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 in the removal process is to remove this breather hose right here by depressing on this gray section and pulling towards the firewall. It just pops right out. Next, remove the two 10 millimeter bolts holding on this factory induction tube.
To remove the temperature sensor here, what we're going to do is just lightly twist it counterclockwise 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. On the inside here, I'm just gonna grab ahold of it. Twist it lightly counterclockwise, I think 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 push pins holding it on here, and 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 removal tool on it, just pop it up.
There you go.
Up by the throttle body there's going to be an 8 millimeter bolt that holds on this band clamp from the soft part your induction tube. Using an 8 millimeter socket to get it pulled off, or you can use a flat head screwdriver, 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 10 millimeter 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 kind of work on it a little bit and it will pull right out.
The first step of this is actually going to be to grab your oiled filter and put it inside of this housing. Now it actually twists in and locks in there making it a really nice feature to have, I'm just going to go ahead and put it in there and now there's little corners on there that actually go into the slot. You'll feel it go in there all the way, and then turn it. And it drops in. You actually feel it drop in a little bit, and now this will not pull it out, you can clearly still see it through this window right on the side and we can now put the tube in the jeep and keep going with the install.
We're going to now install this bracket here onto our intake box. Now, you've got to be careful when you do it. At this end of this bracket, there's offset holes, so one's at the top and one's here at the bottom. We're gonna twist it with that offset hole at the top, pick this up, and it's actually gonna mount just like that using the supplied bolts, we're gonna bolt it down and as you can see, the holes line up if I can hold it straight. Right there they're good to go, we'll put the hardware in there and then put the bracket on the bottom, get those bolts mocked up. Once you get them started by hand, then they're actually gonna use a 10 millimeter socket to get them tightened up.
Okay. Now we're gonna turn it over, put some hardware on the bottom here. The rubber pieces here are going to go up from underneath, in through, and then get a washer and a nut. This is actually what's gonna fall into that bracketry that's underneath where your factory air box went. Just slide it in, put a washer and a flange nut onto it, we'll get it snugged up. Use a ratchet to get it fully tightened up. We're gonna put two of them on here.
Place your intake box into place by pushing it into the factory location to the grommets, and it will freely stand a little bit, kind of fall a tad bit, but we're gonna put that tube in and 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. Put the clamps to both edges. Now we can go get our intake tube.
Grab your induction tube and use the provided grommet to place in this hole here. Work its way around until it's fully seated. You can actually feel inside the tube, make sure it's all the way good to go. This is where your temperature sensor is going to go. Make sure it's nice and tight and a good seal. Before you can put the tube into place, make sure you slide a band clamp over this end, then we're gonna actually put it onto the intake side, right under the throttle body and get it pushed all the way in. Now we can push it down over our new filter. Get it fully seated.
Get the band clamp up top here fully into place. I can get them all tightened down. I'm just going to use an 8 millimeter socket to get them tightened up, or a flat head screwdriver. You also re-install the temperature sensor at the same time. To re-install the temperature sensor, basically just twist it in very gently. Make sure that that grommet doesn't go inside. There you go. It's fully seated. Re-attach the breather hose simply by sliding it over and you'll hear a click. Now you can take down the last band clamp.
Once that's fully tightened up, you're installation's complete.
That wraps up the installation of this Injen power-flow cold-air intake onto our 2018 JL two door, and honestly this is a really nice intake kit for you. It's gonna increase the horsepower and torque of your jeep. According to them, almost 11 foot pounds of torque and 9 horsepower, so not bad. The install was super simple, took about two hours, and before you know it, you'll be back on the trail.
