    Review & Install Video

    Improved HP and Performance. The Injen Evolution Cold Air Intake has a standalone air filtration chamber and an inbuilt supernano-web filter minder that provides an accurate reading for your next cleaning project. It matches the OE style and integrates with factory components while providing an enhanced performance.

    No Computer Reprogramming. This Cold Air Intake by Injen Evolution is designed to offer you a custom upgrade that requires no computer reprogramming for your 3.8L Wrangler. You can add an optional custom tuner with a handheld tuner to gain optimum performance from this cold air intake.

    Reusable Dry Air Filter. The biggest problem with greased filters is that they coat the stainless coupler. That reduces the efficiency of the system. This Cold Air Intake has a dry, rotational-molded polyethylene filter for increased air flow and filtration. The filter is reusable with low maintenance. Servicing is carried out between 10,000 and 20,000 miles.

    Hassle-Free Installation. Injen Evolution's Cold Air Intake is engineered to be an exact fit for the OE factory air induction system. Installation is easy with simple tools. No modifications are required.

    Warranty. Injen Evolution guarantees this Cold Air Intake system free from defects and flawed workmanship with a limited lifetime warranty.

    Application. The Injen Evolution Cold Air Intake fits all 2007-2011 Jeep Wrangler JK Models with a 3.8L V6 engine.

        will a AFE oilless dry air filter fit in the box?

        • The Injen Evolution Cold Air Intake uses their filter, part number X-1071, which we unfortunately do not currently carry. The filter is 4" F x 6" B x 5" T x 9.125", so any filter with those basic dimensions should fit.

            Best purchase

            The pedal response has improved a lot and the intake makes a deeper sound from under the hood. It added about 3-4 mpg. I also feel a huge difference in my acceleration up hill, it’s a lot easier on the engine.

            Lets the motor breath

            The install took no time at all since I already had the old air intake removed. If you do the same thing like I did hang on to the airflow sensor. This doesn't come with a new one. The box fit is a little loose for my liking, It doesn't grab and snap into place were the factory unit sat. Decent build and nice concept overall I think. This is pre-fitted for a snorkel if you plan on that. I did not.

            Love this COI

            So far so good. Love the way it sounds. Not overly obnoxious and feels like there is a touch more giddy up on the throttle. Install was pretty straight forward, DO NOT FORGET TO USE WASHERS WITH GASKETS when mounting the air filter inside the protective case. Instructions don't make mention of them but there are 4 screws and 4 washers so pretty clear on where they're suppose to go.

            Nice upgrade

            Bought this for my 08 rubicon when I switch to 35s easy to install and nice upgrade. Hard to tell how much it helped after I switched tire size but nice either way.

            Improved throttle response (not drastically, it’s a Jeep.) helped MPG, and made them engine bay on WOT, sound amazing!

            Awesome. No regrets.

            All of the parts were well built and fit great into the engine bay. While driving there is a noticeable increase in power and sound. As for mpg increase, I haven't gotten the change to test it. Reguardless im happy with this purchase!
