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.
