    Review & Installation Video

    Review & Install Video

    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.

    MichaelA

    • 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.

    Will this set up work with the barricade roof rack if I install the snorkel in take

    Picklez

    • The Injen Evolution Cold Air Intake when paired with Injen Deep Water Snorkel would not be compatible with the Barricade roof racks due to how far forward the roof rack will push out. If you are looking to pair a snorkel with the barricade roof rack I would recommend the Rugged Ridge Modular XHD Snorkel Kit. https://www.extremeterrain.com/rugged-ridge-xhd-snorkel-jk-1775621.html This model is for the 12-18 Wranglers.

    do you recomend this over the Injen powerflow?

    CraigI

    • The Injen Evolution Cold Air Intake will provide a better sealed filter location which will be very useful in environments where mud/debris are prevalent. We typically will recommend this over the Power flow for any Jeeps destined to run off road often.

      Well Pleased

      Probably one of the most easiest installations of CAI I’ve done so far. Instructions were clear as day, easy to follow. Gain 1.5 MPG running on 33s no lift. So pretty much brought my wrangler back to stock MPG so it balances out very nice. Gets up and goes, with the increased throttle response.

      Air in take with options

      I have a 4 month old jeep and I had a snorkel on my old car and really wanted one on my jeep but just couldn’t cut a hole in my jeep just yet and this is the best way so when I am ready to cut a hole in my jeep I can just get the snorkel and have the fewest amount of connections for water to get in

      Injen cold air intake

      After extensive research on Cold Air intakes I selected the Injen because it's air filter appeared to be will housed. Hopefully, preventing the wet air filter problems others are having in inclement weather conditions. To date no problems. Easy to install, most time spent on removing and installing the 02 sensor. Love the sound, and quick throttle response. I highly recommend the INJEN COLD INTAKE!

      Injen evolution cai

      I do like the sound it produces when stomping on the throttle. But I drive a manual jeep and I think this item would be geared better towards automatics. Driving down the highway there's an awful droning sound after a while this is extremely annoying. Also at times I feel like it is choking rather than breathing better then stock, especially that even after a week of being installed I've lost gas mileage. Install took about 2 hours only because of the air sensor not properly fitting into the gromet provided.

      Nice

      Seems to have a little more power and maybe 1 mpg on the fuel economy with 35" tires. Makes the engine sound more powerful also. It took about 45 minutes to install and fit like a glove. All in all I do recommend this intake.

      nice product

      super simple to install, took about half hour. the engine seems to have more power plus a.m.g. increased a lot. only downside was shipped with wrong coupler to attach to airbox, called injen they sent replacement less than a week. I also don't like how the sensor attaches, factory has a twist and lock, with injen you have to force it into a rubber grommet which doesn't seem very secure. All and all I like the the intake, except how the intake secures. hope this helps anybody thinking about this product....

      Great product.

      Easy install took about an hour with a screw driver and torx set. Fits in perfectly the gromet for the air sensor is very tight. I used a very small amount of wd-40 on my finger then I wiped it on inside of the grommet. It will take some force and manipulation. That is the hardest part. Make sure you have a bent Allen key set for the protective visor.

      I bought this system because I wanted a snorkel but had a hard time finding one with cold air intake (1st part of 2). Very easy to install, and you will notice a slight increase in acceleration. Notice I said slight. All in all its a good product for what it is.
