... cars just don't seem to get much louder. That with a K&N would be maybe 30-40% louder then all stock. You could remove the snorkel thing that goes from the box to the radiator support as well, but then you're eating hot engine bay air. .... Would I be better off with a short ram beacause it rains so much here? I had a bad experience once with a CAI and my last car, Integra GSR and I don't want to go through that again in my WRX...any advice would help...thanx. Offline ...
