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.

Posted by Jim Chrisawn on May 29th 2023
In my opinion this is a much needed addition to the 6637 kit. As usual from Clay top quality material, fit, and function.

Seems of good quality. Only had it on for a couple weeks. We’ll see how it is next year. No complaints so far.

4 ITS OK

not what i expected. My old one was a draw string type, this one has an elastic and it doesn't really fit over the filter well. definitely went the cheaper route in manufacturing.
