The Original and Still the Best
RPi Ram Air Induction Kit - BMW Z4 M-Coupe/Roadster
MFG PN RP-I1004S
Ram Air Induction kits from RPi includes a high performance BMC air filter (oiled cotton gauze), a dyno tuned ram air scoop (choice of red or black) and a 30 day money back satisfaction guarantee.
Convert your stock intake system to a ram air system with RPI's ram air scoop. The RPi ram air system captures incoming air from behind the front kidney grill and forces it into the factory intake ducting. The pressured cold air increases engine performance and efficiency. Expect approximately 8-12whp at 70+ mph winds.
