      Review & Installation Video

      Ryan: The Injen Power Flow Cold Air Intake with the Dry Filter and the Polished Tube is for those of you that have a 2018 and up JL with the 3.6-liter engine that are looking for a cold air intake to squeeze a little bit more power out of your engine. This is going to be a nice simple one out of three-wrench installation and we're gonna show you how to do it in just a second. So, the idea behind any sort of cold air intake is to get more air and to get the coolest freshest air to the engine possible because that colder or fresher air is going to be more dense allowing for more fuel and therefore, more power. Now, Jeeps, really vehicles, in general, from the factory are usually pretty efficient but by adding something like this you are going to be able to squeeze a little bit more power out of it, you're going to be able to squeeze a little bit more efficiency out of it and you may even get a little bit more throttle response as well as a little bit more intake noise from underneath the hood. So, certainly, some benefits to running something like this. Now, the only downside if you wanna call it that is if you do some off-roading in wet situations, you do a lot of water crossings, a cold air intake may be not be the best option for you because it does create a little bit of an easier path for water to get into the engine which can be catastrophic where the factory airbox is going to have a way to help protect the engine a little bit from water entry. So, do keep that in mind as well.So, when you're looking at cold air intakes, you're going to find a couple different options out there, some are gonna be just a plastic tube with an air filter on the end of it, that's it, some will have a little bit of a shield, again, to help pull cold air and not hot air from underneath the engine bay, some are going to be a full sealed box like this with a very specific spot for the intake. And again, that's what we have here. So, this is gonna be a little bit more of an expensive system for a few reasons. It's going to have a metal polish tube instead of a plastic one and it is going to have a full airbox here instead of just a metal shield. So, again, drives the price up a little bit but you are getting a few different features for that. Now, again, this is the dry filter in here as opposed to the oiled one. Sometimes people like the oiled filters because they're able to catch some smaller particulate if they hit that oiled surface, they can stick a little bit better. Other people prefer a dry filter. Regardless of what you prefer, Injen has you covered. You can get this with the oiled or with the dry. Again, this just happens to be the version with the dry filter on it.So, this kit is going to be a little bit more expensive than some of the other ones out there for the reasons that I mentioned before. Metal polished tube, full airbox instead of just a shield. This comes in right around $330 mark. I think that's going to be pretty fair for what you're going to get here. Injen is known for building high-quality stuff and as I mentioned the features do warrant a slightly higher cost. If you want a cold air intake and you wanna spend a little bit less, you can find some with the plastic tubing and not a sealed box, that will save you a couple of dollars. But for what you're getting, I think the price tag associated with this one is going to be pretty fair. As I said before, very simple to get one of these installed on your Jeep. We're gonna show you how to do it right now.Man: Tools used for this install are: 3/8 impact gun, 3/8 ratchet, short 3/8 extension, a panel pry tool, 10-millimeter socket, eight-millimeter socket.Today I'll be showing you guys how to install the Injen Power Flow Cold Air Intake for your 2018 Jeep Wrangler. All right. First thing we're gonna do is obviously open your hood up. We have our hood open here. We're gonna locate the temperature sensor in the intake tube here and we're gonna disconnect this harness pushing in on the tab and pulling straight out. Once you have that undone, we come right here and remove these two push pins. Next, we're gonna go right over here to the crankcase pressure line. Push in on the gray tab and pull straight back. I have a 10-millimeter socket on my impact gun, I'm gonna remove these two bolts right here on our intake tube. All right. Next up we're gonna remove this 10-millimeter bolt securing the airbox to the vehicle. I have a 10-millimeter socket on my impact gun. Next up we're gonna move to the clamp at the throttle body. This is an eight-millimeter nut and we're gonna loosen this. And we actually have one more line to disconnect right here. All right. Now, we should be able to lift the entire assembly right on out of here.First thing we're gonna do is remove the factory air temperature sensor out of the factory air intake tube. You wanna very carefully pry back on the sensor and spin it counterclockwise until it stops. And once you reach that point, you're gonna wiggle it very carefully to release the little rubber O-ring that's inside the tube here and that's it. We're gonna save this for a couple next steps here and it's gonna be installed into our new cold air intake. Next thing we're gonna do is take the bracket and the provided standoffs and we're gonna bolt the standoffs onto our bracket here. All right. We can tighten these up with a 10-mil. All right. We can now bolt our bracket right up to our airbox here and we're gonna use the provided M8 bolts. All right. We're ready to install our airbox. Now, we wanna make sure that we get these two black standoffs into the holes down in the Jeep here where our factory airbox was mounted to originally.All right. Next thing we're gonna do is install the straight hose coupling here. Make sure we put two hose clamps on it. We're gonna go right onto the throttle body with this. Make sure our Injen logo is straight up. All right. And we're gonna leave these clamps loose for now. All right. So, now we're ready to install our intake tube. I'm gonna put a hose clamp down here on our air filter and I'm gonna slide out tube right on in here, we'll get it started into our air filter. Then right from our air filter, we're gonna go into the throttle body. All right. Once you've got your tube situated where you want it, we can take our crankcase ventilation tube and plug this guy right back in. We're just gonna push it in. All right. We got an eight-millimeter socket here with the two clamps on our throttle body and one more down here at our airbox. All right. Last but not least, we have our temperature sensor where you're going to stick it into the grommet on the intake tube and find our harness that we unplugged earlier and we'll plug this guy right back in. And the plug can only go one way.All right. That's gonna wrap up our review and install. Be sure to check out more at

Just bolt it on and you're ready to go.

      1 Top Rated Question

      Undoubtably this product looks amazing, both visually and in the Dyno stats. I do have questions about its design and performance however. With the large opening in the side of the air box, how does this compare to say... the K N 63 where the opening is oriented higher and upward? Also, I am concerned about its continued performance when the engine is hot as the metal induction tube will likely heat up. Will this have an effect on the engine? Again, really love the look but having a hard time pulling the trigger with these questions in mind. Thanks in advance!

      • Both cold air intakes in question are geared/designed towards offroad and general performance applications. I wouldn't worry about how either product acts under stress or getting too hot or anything like that as both K&N and Injen have tested and designed their cold air intakes to withstand these pressures and still offer solid performance.
