    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.

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

    • 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.

      Moderate Satisfaction

      Purchased the Injen intake for my Wrangler. Seems to be a well built component except for the method of installing/securing the O2 sensor in the intake tube. The method provided is to simply push the sensor through/into a 7/8” grommet in a hole in the intake tube. There is no positive “lock in place” connection to ensure the sensor doesn’t eventually vibrate out or get pushed/sucked completely into the intake tube. Compared to the OEM twist-lock method of securing, this is a flawed design. I sent a tech request for another solution via the communication provided by Injen, but, no response whatsoever. Might give this product a second look if you’re concerned with rock-solid performance.

      Sounds Beefy and Small MPG Gain

      Fairly easy install, only issue I had was the UAT sensor. It was difficult shoving it in the rubber o-ring they provide you. I mangled it up pretty good getting it in there. It still worked, but I ended up junking it and purchasing a new one from Extreme Terrain. It was still difficult to get in, but i was a little more cautious and didn't loose my patience.

      Install took about an hour with with just hand tools. Increased MPG by about 1 - 1.5 mi/gal. A lot of bad weather where I live so I went with the enclosed air box for the added safety. Overall, very satisfied!

      Typical Injen, very good stuff

      Everything in the other reviews is correct. Easy install, well designed, only speed bump along the way is the sensor (used a thin layer of dishwashing soap to ease that process). Looks good. Doesn't have the gasping of air sound that the Injen on my Si had - but you get on the gas on the on-ramp and this thing literally roars. Haven't noticed a change in MPG yet but I do feel as though some lag I had in acceleration is gone. Placebo effect? Time will tell. Changing the filter will be a pain as it will require a partial disassemble but otherwise I continue to be an Injen fan. Now taking donations/contributions toward the snorkel... :-)

      Exactly what I needed

      I did a lot of research before buying this. I don’t know about mpg or what the overall gains are. But this is what I do KnOw. When I got in my Jeep and hit the gas I got the pickup I needed. That sluggish get up and go hill that you feel when you are running stock is gone. Install was easy. The only challenge was removing the OEM sensor. Note: if u r removing that chip from factory tube. Turn it counterclockwise. Ever though it says clockwise. Very very happy. And sounds good.

      Injen CAI

      Install took about an hour some details left out in the instructions but it wasn't difficult to figure out. For example... removing the sensor from the old tube. You have to lean the sensor housing back enough to clear the plastic tab at its base and then turn counter clockwise or opposite the arrow on base. Also inserting the sensor into new tube is a little difficult, try wetting the blue rubber seal a little on sensor so it slides in easier. I've had it on a week now and I love the sound it has a deep growl when you get on the gas. Almost cant believe its the same engine. Haven't checked the mileage difference yet but don't really care, sound is worth it.

      Injen Cold Air Intake

      Shipped fairly quick. Very easy to install. I pre-assembled most of it the night before, to save time. Very easy next day swap out. Very noticeable growl on acceleration. All parts fit perfectly. Great quality with every part in box. Have not tracked fuel efficiency, but was not concerned with it anyway. Was more concerned with sluggish acceleration from a stop.

      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.

      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!
