  1. The best bang for the buck air cleaner for a 7.3 5 Star Review

    Posted by 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

    Easy install. Huge air flow. I miss the stock look but appreciate the air flow. Highly recommend. Thank you.

  3. Fast Install and Great Product 5 Star Review

    Posted by 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.

  4. What a difference! 5 Star Review

  9. Best mod for these trucks 5 Star Review

    Posted by on Nov 4th 2017

    This is the easiest and best mod you can do to these trucks. It is something that wakes them up. I love the sound of these filters and how efficient they are. The stock unit on my 02 Ex was full of dirt and filter would not stay clean. This filter keeps the truck breathing and stays fresh and clean. It is a must also with this pricing.

  10. Awsome 5 Star Review

    Posted by on Nov 1st 2017

    I bought this kit to replace a kn filter that was on my truck when I bought it. What an upgrade !! I tell all my friends where to buy this kit. I definately will buy from you again, great shipping to considering I live on the East Coast. Simple to install to.
