    Hands down the best option in aftermarket air filters. I immediately noticed a change in performance and the motor is happier on take off and not so sluggish anymore. Pro- Cleaner air and peace of mind. Con- None but the turbo sings nonstop to you!

    A must have upgrade

    Posted by Unknown on Sep 19th 2018

    I installed the upgraded filter kits to both my 7.3 power strokes from riffraff diesel about five years ago and they work amazingly. These filters keep the intakes clean, affordable and super easy to replace.

    Cheapest price around.

    I have bought in 6's at least 3 times now, saves you a buck long term. Riffraff is the cheapest price I have found for this filter.

    First time buyer

    Posted by Diesel Doghouse on May 30th 2018

    It fit just fine. First time ordering one and wasn't sure what to get, on line chat was very helpful!! Was not damaged in the shipping, they even included, unabashedly, some RiffRaff stickers for their own advertisement. LOL
