OK here is the way I see it... I know "Here goes FirebaseD again" but... if you are wondering if an aftermarket air filter would increase your HP.. It is very simple... Before you spend your money.. Remove the filters you got and run your Crossfire up and down the highway a few times and see what you think.. Its just that easy. heck when I was a kid it was nothing to remove the air filter from my ole man's car and drive it all over the place on the weekends, may not had done anything for the HP, but the sound the engine puts out during full throttle would knock your socks off.

Point I'm trying to make is try the car without the air filters, and if you see improvements... then buy the K&N filters. hooah
