This is the K&N Filter Airhead Mod

I took a Dremel grinder and grooved the front of the filter body, where it contacts the rear edges of the starter cover. At the bottom its about 3/16 - 1/4" deep, tapering to zero at the top, Basically you want it deep and wide enough to not contact the starter cover, therefore not warping the filter.
