NONE, the 6637 has far more surface area to filter which leads to less restriction. I noticed very slightly lower egt temps and better response when I switched. Power difference was not noticeable under 20lbs boost, but above it seemed to black smoke less when i had it cranked up which means more air Is going into the engine
