Where's everyone who tried to crap on me for opening up my airbox? K&N does the same thing, charges $270, people like it[wth]
Clever marketing though. New airbox lid and open ended filter, charge $200 more the just putting the filter into your old airbox and use OE lid. I would bet a dyno of K&N lid to OE lid would be identical.
