cool I think thats what im gunna go with. I believe if im cleaning the filter more then that mean they are catching more crap that is not going into my engine. Just dont trust the K&n's for the Shee. I would rather get 1 mabye 2 less Hp and catch alot more crap than flow that much more stuff through my bike. I hope to get 3 years b4 I put a new top end in it but i would be happy with 2. Cause I know when I get my Dune / Drag bike this fall im gunna be doing it every year.
