I had my car shop "Griffin Motorwerk in Berkeley" Make me a custom ram air intake. U know the little orange vents at the bottom front end of the car... well on the passenger side i had the vent removed and put a noeprine tube in where that little orange vent used to be. the tube runs from there to the stock pletum that i still use with the stock filter. works grate the only worry i have is going throught big puddles but even in the rain i have had no prolbems for the past 16k. I change my air filter a little more often because it seems to get dirty faster but that it.
