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.

This fit as advertised, and brightened up the engine bay a little bit.
Probably does add a little extra filtration to the 6637 filter.
