well, it aint no K&N thats for damn sure! and flow rates of these knockoffs are probably horrible anyway. I beta piece of paper will rip in a lil while and get sucked thru the maf screens, into the TB, go thru the intake, get caught in the butterfly, sit there for 3000 miles, get a bunch of nice carbon built up on it, and then get sucked into the block as a big chunk, then crap out my piston. dont think its worth it lol.
