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.

Great addition to my 6637 mod .Looks the part in the engine bay and is worth every penny for extra filtration it provides. Thanks RIFFRAFF!

quality as always
Fits like a glove, excellent prefilter for the 6637 filter. It's an added layer of protection I wouldn't run without, plus it just looks so good under the hood. Love it.

Great product
You can tell this cover is made with quality material not the cheap imported crap. Looks real clean and brings everything together under the hood. Once again a good quality yet affordable mod that adds longevity to your air filter.

6637 cover
Purchased this cover for my 97' a well as my 99'. Quality product, quick shipping response, and an extended filter life. I highly recommend the riffraff 6637 cover to anyone running or installing the napa 6647 air filter.
