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.

Great working and Very Stylish!
I bought this product out of curiosity just to see how well it worked. The package arrived very fast. After getting it all installed and running it for a few weeks I can say that THIS is a good product. You can easily see the larger junks of dust and debris lodged in it. Best part is, the quality. The nice logo and just overall quality of the material make it a very nice working and looking product. It even helped grab attention on my Instagram page. All and all, Amazing product.
