    6637 air filter

    Posted by Jeff Vounov on Aug 14th 2021

    Good improvement over stock box with K&N ….
    Would be a 5 star if it were washable/reusable , such as the AFE big boost but definitely a good product

    Easy install.

    I wanted an affordable kit that kept the stock PCV equipment. This is it, and looks good too. My old 7.3 is breathing great without the restrictive stock airbox, Easy install too.

    6637 Cold Air Intake Kit

    Posted by Rick on Jul 13th 2021

    This Cold Air Intake Filter Kit certainly improved the intake flow and was very easy to install. I got the kit with the blue filter and everything fit together as expected without any issues.

    ... I can do to my 7.3 power stroke. Riffraff makes it easy with their kit. Best investment ever.
