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.
Installation Note: Take care installed over filter elements with metal cages as a metal snag can tear your cover.

6637 Replacement Cover
Great product, well made and looks great under the hood. For those of you that are running a similar size filter to the 6637, take into accouter whether it's open at the front or not. For example: this product was designed for the 6637 which is not open top, so the cover doesn't cover the top portion of the filter just around the circumference. This product will fit the AFE Big Boost but won't cover the top which it also gathers air from. I have the Big Boost and I still purchased the product, it helps. I would recommend!

Slick as snot on a doorknob.
I really like the cover, it fits perfect, and looks great. No more questions where I got it either. Haha.

Much Improved
When I ordered my first filter and cover about three or four years ago, the cover had a drawstring at one end and was sewn shut at the other. The current covers have drawstrings at both ends making them much easier to remove and clean. I am impressed by the continuing redesign and improvement of the products offered by Riffraff.
