6637 Replacement Cover - Red
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.

NICE COVER
I ordered the red cover mainly for the look. Not really needed especially if you order the afe filter since it is blue in color. The red adds a nice touch to the engine compartment and also aids in keeping anything large from getting wedged in your filter pleats. Get one.

Dresses up the air filter nicely
This filter cover is well made and looks good. It does its job of keeping larger debris out of the filter and dressing it up.
