installed my bmc race filter a while back when also installing my brocks full system streetmeg/pcv on my 08. Can't stop worrying about the race filter in there letting a bunch of crap in. I'm sure it won't cause any ill effects what so ever by the time i sell the bike, but i can be a little ocd at times lol. Could care less about an xtra 1-2hp using a race filter, just want to make sure the engine is well protected. Have read great things about pipercross filters, was thinkin about tryin one out or re-installing the stocker, what do u guys think. My options are: deal with my ocd dilemna and the bmc race will be just fine, purchase another filter (pipercross)?, or re-install the stocker
