The K&N Generation II F.I.P.K. (Fuel Injection Performance Kit) short ram intake for the BMW E46 M3 combines the efficiency of a high flow K&N air filter with an induction system optimized for a smooth air intake flow. K&N uses the largest conical air filter able to fit under the hood of your M3 to maximize filtration and allow the 3.2L engine to take in as much air as it can handle. A custom heat shield protects the air filter from hot, under-hood temperatures to ensure a cooler intake temperature. The air filter is attached to a rotationally molded, high-density, polyethylene intake tube to enhance the intake charge by creating an air stream, free of power-robbing turbulence. The performance of the FIPK intake system has been dyno proven, creating more than 17.8 horsepower on a stock 3.2L M3. You can't argue with numbers like that from a short-ram intake. K&N Generation II FIPK intake systems for the M3 is legal for street use in all 50 states, and mounts to the factory intake mounting locations with common hand tools. All necessary hardware is included for a complete and clean installation.
NOTE: K&N 57 Series FIPK's are street legal in all 50 US states.
