I just wanted to bring it to people's attention that the Boss intake works extremely well at sucking in air. As a result, it also sucks in anything and everything you drive past! I have found massive amounts of leaves, twigs, bugs, rocks, dirt clods accumulated in my filter after every track day. I just popped mine out the other night after doing all the track prep for this weekend and everything but the kitchen sink came out of it. It was unbelievable. I'd suggest you knock the debris out of your filter on a regular basis.
