I ran a test in a test unit for air filters. Tested the the stock filter and the air flow was very low, set the BMC race filter in it and the air flow was a differenc between night and day. I bought the one for my 2003 ZX-6RR (BMC Race filter 323/04 RACE.. http://www.bmcairfilters.com/VisModel.asp)Originally posted by devulge
Does Kawasaki use paper or foam air filters? BMC has air filters for the bike ('03) & I will replace it if its paper, but not if its foam. K&N filters suck, so I wont even go there.
