I'm Ryan from extremeterrain.com, and this is my review and installation of the Injen Evolution Cold Air Intake fitting all 2012 and up JKs. Today we're going to talk through the installation of this cold air intake which is a very simple one out of three wrenches, and we're also going to talk about the construction and a few of the features. The idea of a cold air intake is that it draws colder air into the engine allowing the engine to make more power and that it can also open up the factory air intake system so that it can blow more air, again making more power. Systems like this on the Jeep are really going to give you a little bit more throttle response, a little better MPG, and also give you a little bit more noise from underneath the hood when you get hard on the throttle. The power that you gain is really going to be at the top of the RPM range where we don't spend a ton of our time. This system, in particular, is unique for a few different features that it has and also some add-ons that you can get for it. This system is as you see a cold air intake with the box underneath the hood. However, you can get attachments onto this box if you choose to purchase them and to cut your hood which will turn this into a ram-air intake setup or even a snorkel setup. Both of those will be drawing air from outside of the engine bay which will actually be cooler, so those will also give you a little bit more of a power increase. This system is made of roto-molded polyethylene, and the filter that comes with it is a super nano-web dry filter that is one of the larger filters available on the market. When you combine that with the fact that this is a fully enclosed airbox with the exception of, of course, the air inlet itself means that this system, at least on paper, is going to do a good job of drawing the coldest air possible for a system that is still drawing air from inside the hot engine bay. If you go ahead and bolt either the ram-air attachment or the snorkel air attachment onto this system, it will do a really nice job of drawing the coldest, outside of the engine bay air, into your engine. One of the things that makes this system unique, as I mentioned before, are those attachments that you can purchase. Something else that makes this unique is Injen's little indicator that's on the airbox itself that will tell you when your filter needs to be changed which is actually kind of a nice feature being that this system is completely sealed. You do have to do a little bit more disassembly in order to get the filter out to inspect it. What this does is actually read a pressure differential. It reads vacuum between the inside of the filter and the outside of the filter to let you know if the filter is being restrictive or not. I personally can't say how well this works, but again, in theory, it's a nice little addition. Getting a cold air intake installed on your Jeep is going to be a very simple one out of three wrenches. All you'll need to do is first remove your factory air intake system which starts by removing the engine cover which you'll just give a good pull to remove. Then, there are a couple of clamps holding the factory tubing in place. To get the factory airbox out you really just give that a tug and that will come free as well. After that, it's just a matter of installing a new airbox, your new piping, and your new filter all into the Jeep. This does come with all stainless hardware that you'll need and all urethane couplers to make sure that everything is going to fit properly. When you take the factory system out, you will have to take your air temp sensor out and reinstall that into this cold air intake. It does have a spot for it. But other than that, this is really a very simple bolt on system that shouldn't take you more than an hour to install with traditional hand tools. There are a few cold air intake systems on the market that are just a tube and a filter. Those are certainly going to be less expensive than what you see here because they simply have fewer parts. But, for a system that includes somewhat of an enclosed airbox system, this is right around the same price range as a lot of the other ones that you'll see on the market. With the way that this one is molded, the way it's put together, the hardware that they give you, it seems like it's a really nice system. In my opinion, this is a lot of money to spend on a cold air intake on your Jeep that again is really going to provide miles per gallon, a little bit of throttle response and also a little bit more noise from underneath the hood unless you're in the top of the RPM range. However, for those of you who are interested in those different features, this system is going to do a good job of drawing the coldest air possible for an under the hood cold air intake system. That's my review of the Injen Evolution Cold Air Intake System fitting all 2012 and up JKs that you can find right here at extremeterrain.com.

Injen Air Intake
Sounds good. A little additional horse power on top end. No noticeable change in gas mileage. Would only get this for the sound and horsepower.Helpful (0)

Do it for the sound
Easy install. Put everything together the night before which took about 10 min. Install next morning in about 20 min. Only stupid mistake I made was trying to push the temp sensor too far into the intake tube rubber grommet. The sound is great. I have a dual axle back exhaust which already sounds good. Paired with this intake the sound is awesome at 3000 RPM. There is also improved throttle response. As far as gas mileage... don’t know don’t care...Helpful (3)

Great cold air intake
Slightly Increased my gas mileage and sounds great. I would probably get better moly but I like hearing it suck airHelpful (1)

Great cold air intake. Made a big difference in throttle response and sounds great. I did also install the Magnacharger axle back exhaust at the same time.Helpful (3)

I recently replaced my exhaust with a dual exhaust. I wanted more power and bit more edge. So I brought this gem and let me tell ya! Am so happy I did. My jeep sounds like a beast now. I have so much power underneath the hood it sounds like I have a caged tiger in there. The installation was simple and took about 30mins to put in. Thank u ExtremeTerrain!!!!!Helpful (5)

Very happy with this product. Simple install and it gives a nice throaty sound when you accelerate. I also have the Air Raid throttle body spacer so I also get the slight whistle sound at the beginning of acceleration. With off roading in the desert I couldn’t see using a open type of CAI.Helpful (2)

Excellent sound, great performance!
This exhaust is great. Took me about an hour to install but would have been 30 min if it weren’t for the darn square sensor going onto a round hole. I have no idea how I got it in, but it’s in now and I don’t want to talk about it. What I do want to talk about is this simple upgrade that added 2 mpg and a whole lot of balls. The rumble shifting into 3rd and 4th makes me smile like the day I bought my Jeep and when I need to blow past a slow poke on the highway, they hear it before they see it. Stop reading reviews and buy this now!Helpful (2)
Is this California smog legal?
At this time the Injen Evolution Cold Air Intake will not be CARB legal.
How does this compare to the K N Series 63 AirCharger High Performance Intake in terms of performance gains? Does the K N gain an advantage for not being fully enclosed in a housing? Also, is the Injen filter washable reuseable? TIA!
Both intakes are great kits, which would give roughly the same gains. The K&N kit is open so you will have less restrictive air flow than the enclosed Injen kit, but for off-roading the Injen will be better protected since the housing is enclosed. The enclosed kit will help keep water out of the engine which can cause the Jeep to hydro lock.
Is this a bolt on system for oem. That is no drilling etc. Thank you.
This intake will be a bolt-on installation that will not require any additional modifications or drilling.
Is there a specific filter that needs to be bought or will my Jeep Dealership be able to replace as needed when being serviced?
This filter can be cleaned and does not require regular replacement. This kit includes a top mounted filter minder to give you an accurate reading on your next required cleaning. The filter minder provides a simple way to check your filter's status over disassembling your air box for a visual inspection.
will I need to tune up my engine after installation?
You will not have to tune your engine, however we do recommend a tune after changing something like this on your vehicle, so that you will get the best performance possible.
The Injen Evolution Cold Air Intake should be inspected twice a year depending on the amount of driving performed and it should be changed according to its condition the standard maintenance interval, whichever comes first.
