Finally someone got it right. More air means more fuel.
I have a question to the moron that said its January its 30D outside. Go out warm your car up and pop the hood. Is it 30D under there? Didnt think so. Your best bet is to go with a Cold Air Intake(CAI) not the short Ram Intakes because of the fact that you are inhaling warm engine bay air. A CAI will bring the fliter element away from the engine and closer to the ground or the side of the car where it can pull colder air(from our January 30D air OUTSIDE the enigne bay). Also Im not sure about this but would the longer tube on the CAI also give more low end torque?
