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.

Filter cover does its job
If you are looking for a cover for your filter that fits, does its job and is available in fancy dance colors - this is it. Highly recommended for ANY large, 6637 style filter as it protects it from excessive external wear issues.

Sets off the filter
Got this with the 6637 conversion kit. In my personal opinion makes things look a lot neater under the hood with this surrounding the new filter. I feel more at ease also knowing this will keep the filter cleaner longer and will help the filter to keep the engine clean.

Great cover
Much better Quality than my last cover.
Has nylon pull cinch strings like a sport hoodie for a snug fit.
I chose black, for me it blended well under the hood.
