Sooooo I don't know why it took me this long to notice but behind the stock air filter is a meshed off second filter. Seems like needless restriction to me. I have a replacement k&n filter and think that this is enought so can i get rid of that second and how and also if I remove it will it cause any other problems (besides MAYBE dirt getting threw) Any info is great Thanks:tu:

If you search for "secondary air filter" you'll find a handful of threads. Apparently it's a charcoal filter, part of the emissions control system. Depending on who you believe, removing it will either gain some power... or not. And someone posted that if you remove it, you cannot replace it. Mine is staying put.

I took mine out ~40,000 miles ago and have not noticed any difference. I would leave it.
