( Re: best air filter

CARNZ - UNI foam filter, proven to filter betterthan a K&Nwith anouterwears , and still provides good flow )

I absolutely agree, k & n may have better air flow but that doesn't matter when your sucking dirt and other unwanted particles into your motor. Most foam air filters have much better filtration ( that's what matters most. ) Uni air filters are one of the best, I would also suggest a no toil super flo air filter ( that's what I use! )
