6637 Replacement Cover - Blue

Part Number:



Made to high standards, these covers are designed to extend the life of your air intake filter while also giving you a way to visually see the amount of dust collected.  The covers work equally well on both oiled and non-oiled filter elements to prevent larger debris from prematurely reducing critical air flow to your engine.

    Very breathable material. Great idea for keeping grime off the filter. Nice to know I don’t have to worry about it when I’m working under the hood.

    Outer Wears

    Mostly satisfied with the product quality and price. If they could just make the tensile strength a bit tougher I would give it 5 stars. I’m not a dissatisfied customer though. I just have a small hole in the screen where there wasn’t one before.

    6637 cover

    Wears well (it does wear). Wish the ends closed up tighter but for a product that endures heat, dirt, and constant vibration it's worth it.
