i've got a custom intake, and have the usual farting/mooing/whatever-the-hell-you-want-to-call-it noise.

i read on here somewhere you can buy a K&N crankcase filter or something to help muffle the cows a bit, but i can't find that thread now.

does anyone know the part # so i can order it? the noise was kind of cool at first, but 4 months of mooing is starting to grate the nerves a bit! (still lovin' the "whoosh" though
