Merideth: If you're looking for an affordable and efficient way to upgrade the intake on your 2018 or newer 3.6-Liter JL Wrangler, this Deegan 38 Cold Air Intake in black will be a good kit to take a look into. Now, if you've added some heavier mods to your Wrangler and notice a lack in fuel economy or throttle response, this cold air intake will help out by allowing the engine to breathe better and assist when it comes to adding some of that performance back that you may have lost.This will also be a great option if you're tired of replacing your factory filter and want one you can reuse so you're not constantly doing maintenance to achieve that performance. I do wanna call out that this style intake with the heat shield here is not gonna be as protective as your factory airbox, so I would just recommend this to somebody who's mainly avoiding any heavy mud or water if they're taking their JL off-road.This intake will feature a straight-through style intake tube to relieve a decent amount of restriction and increasing airflow for better fuel efficiency and performance that can usually be felt in your throttle response in the higher RPM ranges with no tune required. This will also feature a reusable filter that I mentioned will cut down on maintenance while creating a cleaner and more efficient flow of air getting into your intake system. In addition to the function, this will also just elevate the styling underneath the hood compared to the boring factory plastics with this unique green filter and all-black look.Now, getting into the build of each of the components here, starting off with the heat shield, this is gonna be made of a durable steel material that will seal to the hood with the provided seal over here. And the intake tube is going to be made of an aluminum build to reduce any heat build-up while boasting a tough black powder coat on top for a stealthy look and also to protect the aluminum and the steel underneath. The filter will also be made of a high-flow, multi-layer sticky media that will be 100% cleanable, and the rest of the kit will come with all of the hardware, clamps, and fittings that you need for a factory-like fit.Now, this kit's gonna come in at roughly $200 and is very affordable in comparison to some other options on the page. Now, a kit like this, it's going to be more on the simplistic side, is usually also going to be more on the cost-effective side. And I like that you're able to save a couple bucks while still getting a very functional system and it's gonna have a no-frill install, so you really don't have to question when it comes to putting this on your JL.Not to mention, it does give the engine bay a sporty aesthetic while adding a very functional upgrade. In the meantime, it's also gonna save you a couple bucks in the process. So, in my personal opinion, I think if you're looking for those qualities out of an intake, then this is gonna be right up your alley.Install is going to be a one out of three wrenches on the difficulty meter, taking you about a half hour to get the job done with some pretty basic hand tools. Now, speaking of the install, one of our customers here has installed this on their JL and is gonna walk you through what that process looks like step by step. That's gonna wrap it up for me. Let's go ahead and get into the install.Matt: The only tools you're gonna need today for the installation is a socket with a 15-millimeter and 10-millimeter sizes, a socket extension, a utility knife, a panel removal tool, and I went ahead and used two straight-head screwdrivers depending on what the reach was and what worked out best for me. You can get by with one.Hello, I'm Matt. Today we're gonna be installing the Deegan 38 Cold Air Intake for a Jeep Wrangler JL 3.6-Liter engine. First step we're gonna do, open the hood. Make sure you put your prop in, don't let it fall on you.Next step is to remove these two 10-millimeter bolts. First socket. All right. The next step is to remove this hose. We do that by pushing down on this gray button here. You push down on it, you press it and just pull the hose off at the fitting. Pretty easy.All right. The next step here is we're gonna remove the air intake temperature sensor. And there's three clips we need to remove with the trim removal tool, these two on the front, and there's this one on the back, which doesn't have anything to do with the air intake, but you'll have a hard time getting this tube out if you don't remove this clip back here.You should be able to gently turn this sensor. If not, you might have to use a pair of pliers just gently turning on this sensor just to loosen it up and you should be able to get it out by your hand. Gently pull that out. And again, just remove this with a trim removal tool. And again, this third one here, you want to get this one out the way as well. Here we go.The next step is to loosen this hose clamp that's attached to the throttle body. So, we'll just take this hose clamp here with a straight screwdriver and we'll just loosen it a couple turns and pull that loose from the throttle body. And the next step is to loosen this hose clamp that's attached to the airbox. Again, just a couple turns with a straight-head screwdriver, get that loosened and then you can just take this entire assembly and remove it from the engine.All right. The next step is to remove this 10-millimeter bolt from the airbox. And then the airbox is held in by two grommets down below. So, you'll just want to firmly grab onto the airbox and you're gonna pull it up. It is gonna seem like it's stuck, but it will come out. And if those grommets do come out with the airbox, you wanna pull those off and put them back in the holes. Put those grommets back where they belong and we'll move on to the next step.For the next step, we're gonna take these grommet studs that came in the Deegan 38 kit and we're gonna stick them into the grommets that we had just removed with the previous airbox. For the next step, we're gonna take our airbox. We're gonna place it over the mounting studs. And we're gonna want to take the two bolts that are in there, we're gonna take a flat washer, a locking washer, just like I have displayed here. Again, that's a flat washer, a locking washer into the in-made bolt.And we'll do that two times and we'll put those into those holes from the mounting studs. Do not tighten them all the way. We'll still do some adjusting after we're doing this step. And again, I just hand-tighten them there, as you can see. We'll do some further tightening later on.For the next step, we're gonna take off one of these existing 10-millimeter bolts from this vehicle bracket here, then we're gonna take this studded bolt here and we're going to screw that into that we just took...what we just took out. We'll screw that in tightly. And then there's a hole on this airbox. We'll line that up, put our stud through there and we'll use this washer and this locking nut to lock that all in place. We can go ahead and use our socket to tighten that up.All right. I'll move on to the next step. For the next step, I'm gonna go ahead and prepare our intake tube. We're gonna go ahead and install this grommet to the hole on the curbside of the intake tube. I'm just gonna squeeze that and get that started in that groove and you can kind of work your finger all the way around and get that snapped into place just like that.And then on each end of the tube, we're gonna install one of these rubber hose fittings and then two hose clamps. One of those hose clamps will go...will tighten this hose to the intake tube, the other one will fit around the intake of this end of the throttle body. And then we'll do the same thing on the other side. Grab two hose clamps.Once we have that setup, we can go ahead and start installing this intake tube to our throttle body on this end. It's a pretty tight fit even with the hose clamp all the way out. So, I'll go ahead and loosen just a little bit more to see if we can get that to fit around that throttle body much better.We'll make sure we get that hose clamp up around the throttle body as much as we can. Make sure we get a good seal and it's tight. [inaudible 00:10:12.175] my screwdriver there. Should be back in there around that grommet there and tighten it up. Put it in all the way until we get everything fitted. But I am just gonna tighten it up just till this feels good. The other hose clamp, we'll make sure we're getting good seal around the intake tube there. And just give it a little couple turns just to get that started. We'll get that situated so that it looks like it's gonna go into the airbox there.For the next step, we're gonna go ahead and take our air filter. We're gonna put this fitting on the inside. There should be kind of a tight fit around that filter. Should get a good seat around there like so. We got our hose clamp that will go around this, go ahead and tighten that up.Get that nice and tight on there, make sure you have good seal. Nothing will come off.So, let's [inaudible 00:11:27.377] in here. We'll go ahead and start mounting this air filter into the airbox. We'll make sure that that piece pushes out on the back side and we'll get our air intake tube fitted.All right. Our next step here is to fit our intake tube to our air filter. So, we may have to adjust these, loosen these hose clamps here to loosen the intake tube a little bit. And then we may have to play with the hose fitting. We get this thing to slide in there once we do. We wanna make sure we get those hose clamps tightened up. Perfect. So, we'll tighten up one fitting to the air filter, one fitting to the intake tube, and then we'll go ahead and tighten up the same ones on the throttle body.All right. The next step here is to install this PVC tube onto the intake hose. You may have to hose PVC, so just have some bend to it. You want to make sure you push that on until you hear a click sound. Make sure you know it's on all the way. Here we go. I think we got that one.We're gonna solve this temperature sensor again. Just for safekeeping, I'm gonna go ahead and make sure that this prong here is facing out like it was when we uninstalled it from the original intake tube. This one we'll just push inside that grommet that we installed in the tube earlier, like so.The last step, we had this weatherstripping material. Most likely be too much, so you'll want to get it started and kind of go down about as far as you can. On this side, it looks like we can go down about as far as this bracket right here. We'll just push that on around all the way up around the top of this box. Just bend it around the corner, press fit this weatherstripping all the way around.Then on this side closer to the front of the vehicle, it looks like it can go down about two or three inches. And just make sure you use some kind of snips or be careful with some razor blade and just cut that off anything excess that you have.All right. We're basically done. Just wanna make sure before you turn your engine back on that we just go ahead and make sure all our hose clamps are properly tightened. Make sure all our sensors are in place. Go ahead and remove...take the sticker on the Deegan symbol there. And congratulations.Merideth: So, that's gonna wrap it up for my review and the install of this Deegan 38 Cold Air Intake in black fitting all 2018 and newer 3.6-Liter JL Wranglers.
