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.

Quality
From hearing about good and bad filters to use. This has got to be the best one I've used, Made with good quality and high air flow technology with 0 chance of ingesting dirt into the turbo. 10/10 recommend, not to mention best price around for a good quality filter.

Great item
It’s only a filter cover but shipping was fast and always a pleasure to add some riff raff under the hood

Filter cover
Keeps tiny particles out and since the 6637 isn't water resistant this gives that extra layer to keep water out, I ran the 6637 for about a week before u got the filter cover and in the rain I could tell some moisture was getting through.

Blue filter cover
Besides being pretty this cover really helps keep pine needles out of the creases of the air filter. I had the AFE air box and filter before and ran into this problem all the time with the pine needles. Good product as usual from Riff Raff

It does what it needs to
It's a filter cover, and it's blue. Looks nice, but I wish it covered the whole filter (like a sock) rather than just wrapped around it like a sleeve.

6637 REPLACEMENT COVER
This eye catching cover, is a reminder I have another quality product from Clay at RIFFRAFF. It fits like a glove over my Donaldson Blue filter. I look forward to testing it’s long term performance as a pre-filter and cover to protect the filter.
