    Must Have

    Posted by Eric on Feb 2nd 2018

    The product is simple, and it works great. Gives the engine a ton of air, and when combined with a tune and a 4” turbo back exhaust, it creates a noticeable power gain. You can really hear the turbo screaming through the intake.

    Installed the filter on the vehicle and it works great. I noticed better acceleration and response.

    The best bang for the buck air cleaner for a 7.3

    Posted by bluesbish on Jan 3rd 2018

    7.3's always suffered from poor air filtration. the factory boxes never sealed up correctly. These kits are a nice looking and affordable way to bring fresh air to a 7.3

    Fast Install and Great Product

    Posted by Darby Weiss on Dec 6th 2017

    So ordered this kit and one the shipping to Nashville Tn was super fast. Once I got the kit in it was like Christmas. The install was fast and easy, it all went in about 15 minutes and is easily one of the best things I have installed on my truck. Going from an S&B kit to this was huge or so it feels on the butt dyno.
