You can get them here FilterCovers
Anything placed over an air filter will create some type of restriction, but in my opinion, it's minimal and well worth the cost. It's amazing how much dirt that pre-filter will hold. I have not heard of anyone having any sort of air restriction issues using the cover.
As for fit, I would have to say superb. I've bought covers for 3 different types of filters and all have fit like a glove.

You can e-mail Pete, but he has told me that he has had testing done and the cover has less than a minimal affect.

I've had my Petes cover for a little less than a year now I think and Chris is right. That thing will hold a lot of dirt. Washes up easily. I have the blue one which Pete said was a higher flow material and I love it! Don't notice any air restriction at all. Definitely worth it!

I have run my filter with and without Pete's hi-flo cover and didn't really notice any effects as far as restriction. I feel the cover is more like an added layer of protection....and looks great, too!

Pete is great to deal with and will put most any kind of graphics on the cover.As Chris said,they fit perfect and work well with the 6637.

I highly recommend Pete's cover. Minimum restriction and added filtering, plus looks good! All pluses in my book.

Ha! Wow, this thread is almost as bad as some crotch rocket forums I go to.
I am planning on ordering either the ford equivalent BFAH(washable but I can't remember the brand right now) and a 6637 w/ a cover for each, or two 6637's and two covers.
I do know that after harvest my truck will have asthma if it doesn't already.

Don't forget, if your filter isn't list in his web-site, he can customize one for you filter application. He built me a cover for my S-B filter cause I wanted the extra protection and looks, like said by Chris, like a glove fit.

Can't take the credit on these, BDrummonds told me about them. If you do alot of miles like he does then you can end up saving $$ over the 6637 with this set up. But you have to drive alot, otherwise the 6637 is much easier.
