      Review & Installation Video

      Hey, guys. Adam here with And today, we're taking a closer look at and, of course, installing the Injen Evolution Cold Air Intake with the Oiled Filter, available for the 2011 and newer 5.7-liter HEMI-equipped Challengers. Check this out for your own Challenger if you're looking to ditch the factory airbox to pick up a cold air intake from the aftermarket world that's gonna help your engine breathe better, give you a nice bump in horsepower and torque, as well as throttle response and acceleration.This particular one comes in just over the $300 mark and, honestly, it's a pretty good option. This one here comes with a washable and reusable oil filter that is not only going to filter out way more than your factory paper element could, 99.53% filter efficiency rate as a matter of fact, but it's also going to be a huge step up in quality. This has an eight-layer cotton gauze finish in red that also has a wire mesh outing to help filter out as much as possible while also pulling in more cold air than that factory airbox could. We'll take a closer look at this comparing it to the factory box in just a little bit.Aside from that, this particular kit is a little bit different than some of the other Injen options on the site. If you're browsing through the category, you'll see quite a few options from Injen alone, not to mention some of the other brands out there. Injen has their wrinkled black, they have their polished finishes with aluminum intake tubing like their Power-Flows, and then they have the Evolution. The Evolution is different in the sense that it uses different materials throughout the entire kit and has slightly different technology built-in.I like the Evolution simply because it uses a roto-molded polyethylene material which is gonna dissipate heat a lot better than some of the aluminum options out there would. So it's gonna retain that cold air giving you a smoother airflow inside because aluminum, while it does have a more kink-free finish than your factory tubing, isn't gonna be as smooth of an airflow as some of the plastic options out there like this one. It is durable. It is super strong. It's heat resistant, of course, which is a huge factor under the hood, and it's also impact-resistant because it is a very durable material.Of course, it's got the Injen name on the side here which I actually like. It's pretty subtle but it lets you know what's under the hood. It also has a location for your air sensor. Now, that sensor, typically in other options in the category will just sit in with a rubber grommet, this actually has a plate to make sure it's oriented properly which I think is just one step further that Injen took their technology to make sure that it has that premium quality.Aside from those two, the last thing I wanna mention here is your new Evolution airbox. This is little bit different than the Power-Flow box you'd see in some of the other Injen options. This has an inlet that's gonna go down a little bit farther. Some of the other boxes that Injen offers and some of the other boxes in the category don't go down as far, so this is gonna put a little bit more effort into pulling in the cold air from under the engine bay for the aerodynamics that are going under your front chin splitter. Aside from that, you have a big, large, clear cutout here that is gonna let you keep an eye on the condition of your filter. You can just pop it out, wash it, re-oil it, throw it right back in, it's as simple as that.One of the other things I like, and this is really just a small detail, I like the small details of some of these kits, it just shows you how much thought and time went into developing these. Some of the other kits out there use a separate bracket that you have to bolt on to the heat box to get it to have this little knob. Now, if you know how it works under the hood with these 5.7s and you've done a cold air intake before, you know that there's a rubber retainer grommet on the inside of the wheel well under the hood for a knob like this to keep your airbox sealed and in place. Some of the other ones use a separate bracket that bolts this up, this is actually built-in. No need to bolt up separate additional pieces. I like when kits like these are as simple as they can be. Very minimalist but still gets the job done with a lot of thought put into it, I personally like that.Finally, it has a lockable filter technology. Rotate that in, turn it a quarter turn and it's locked in place, that will not move around. When it comes time for maintenance, boom, comes right back out. It's really as simple as that. I really like that built into the Injen.This particular option, around 330 bucks, like I said. Install gets one out of three wrenches on our difficulty meter. Anybody can tackle this in the driveway at home and it does not require a tune. That is something you don't have to worry about doing during the install process. Right out of the box, you put it together, throw it under the hood, and you're good to go. It's a direct bolt-on with no tune required. One out of three wrenches. It will take an hour, maybe two at the most depending on your experience. Simple hand tools required. Anybody can tackle it. I'm gonna show you guys every step of the process starting with getting our factory tubing out. So let's get to it. Tools used in this install include an impact gun, a ratchet, 15-millimeter wrench, 8-millimeter socket, 16-millimeter deep socket, and a small Allen key set.All right, step number one for the uninstall, of course, just pop off your engine cover. Now, of course, we're working with a 5.7, this may be a little bit different for the guys out there with a 6.1 but shouldn't vary too much. Just pop off that engine cover and just set it aside.Next up, we're gonna do our sensor right on the side of the tubing that connects to the throttle body, it's really just a pinch and disconnect. From there, you actually wanna remove the fitting for the sensor itself which you're just gonna twist and pull straight back on. This is extremely sensitive so set this aside and just make sure it's out of the way of any danger.Next step here, grab an 8-millimeter socket or a flat-head screwdriver and we're just gonna loosen up the clamp holding the intake tubing to the throttle body. From there, you should be able to just twist it up, pull this back. Before we can remove this, we have one more bolt to remove as well as a hose and then the whole thing will come off in one piece.All right, next step is the bolt holding the factory heat shield to the front support, that's also an 8-millimeter. Just loosen that up and take that out. From here we're gonna disconnect the hose, the breather line on this end. Just gonna wiggle it back and forth and pull it straight back. At this point, we should be able to disconnect this from the throttle body and pull it all up in one piece. All right, this we'll put straight up, pull out of the throttle body. Can lift up on this end here, and we're just gonna set all this aside.Now, this bracket was used to hold onto that factory intake at the extension portion, we're just gonna go ahead and remove it because we're not gonna need it for our aftermarket intake. So I'm gonna take a 16-millimeter socket and just remove this bolt. At this point, you can grab a 15-millimeter wrench to hold the inside bolt. Grab your 16 socket again and just pop off the nut on the outside. All right. This way the bracket's out of the way but there isn't an open hole there, can just thread that bolt back in there and tighten up that nut. Perfect.Step number one here, what we're gonna do is grab that plate with the Allen screws already on, we're gonna lift this up here and set it into place. You wanna make sure you have an Allen key that's small enough to screw these on. So if you have say a 20-piece Allen key set or something of that nature, definitely would help. Just wanna screw these on. Once we get it started, we'll be able to tighten it down.At this point, just tighten those screws down, you don't wanna strip them so just get them nice and snug. Perfect. From there, grab your air sensor, align those holes, give it a twist and it locks into place. That's taken care of. The next step we wanna tackle here is our coupler attaching the tubing to the throttle body.We're gonna grab that coupler and set the larger end over the side of the intake tubing that's gonna go under the throttle body, it's a little bit of a tight squeeze. From there, you'll have three different sized clamps: small, medium, and large. Your large one is gonna go to your air filter, so we wanna set that one aside. The small one is this end of the throttle body. The medium one is gonna go straight over that and go straight to the back end. So if you need to loosen this up, grab an 8-millimeter socket or a flat-head and we can loosen this up and then tighten it down. All right, from here I'm gonna use my 8-mil socket and just loosen this clamp up and slide this over the coupler. Looks like we have to get loose a little bit more. Perfect. From here, we're just gonna lay the throttle body clamp over top. Now, you don't wanna tighten it down too, too much, you just wanna get it a little snug so it holds itself in place. And now we should be ready to drop this in to the vehicle.All right, first step here is actually to grab your heat shield and you wanna make sure you're installing the filter inside of that box like I showed you. That's gonna drop right in and install to that grommet on the wheel well and then it's gonna re-use the factory bolt to go through here to secure that into place. So grab that, tighten that down.All right, the factory bolt is an 8-millimeter so just tighten that down by hand at first. Grab your socket and just get it a little snug. Next step will be to drop in your intake tubing. You wanna set that into the filter first, rotating that into position then downward onto your throttle body. Once you have it set in your filter, set it into your throttle body like this, bring that clamp upward, grab your socket and tighten that clamp down on the throttle body. From there, rotate the clamp upward that's on the filter. Do the same thing.Next step is to grab the hose included in your kit, this is gonna attach to your crankcase breather hose with our fitting here. You just wanna attach this over the end and just push straight down, that will hit the lock there. Same thing on this end. With the factory portion of the hose, connect those two together, grab this, and attach this end to the fitting on the end of your intake, it has that extension built-in.Now there's only two steps left. Step number one, grab your harness, connect that to your air sensor. Once that snaps in place, grab your engine cover and set that over top. Perfect. At this point, you're good to shut your hood and you're good to go.Well, guys, that's gonna wrap up my install and review for the Injen Evolution Cold Air Intake with the Oiled Filter. Check this out if you're looking to ditch the factory intake to pick up a little more horsepower and torque as well as throttle response and acceleration with an oiled filter that's washable and re-usable for your 5.7.
