What are the Micron Filtration Ratings?

This is where the Rubber meets the Road. Maximum Filtration with Maximum Air Flow.

I run the Donaldson Blue 6637 from Riffraff Diesel. It is basically a Donaldson heavy equipment filter the same specs as the Napa version but with a 4 inch adapter to install on our trucks. It claims to flow up to 1300 CFM. BTW, its only available from Riffraff. Don't try amazon as I did the first time trying to save a buck

Riffraff has some great stuff!

Yep work great, but when you start getting into some boost pulling a bit of a load it is amazing how loud it will get. its a bit like having a jet engine under your dash!
