interesting read, doesnt seem like any of them did any better than the others for the most part in the fact that they all let dirt thru turning the 2nd filter black and none really stood out at alll.
it was hard to follow but i understood it. if you go to the main page he did a flow test between the filters and said that K&N filters flow .14% better in atmospheric pressure, which is about 14.7psi
