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.
