The K&N 57-1003 Air Intake fits some BMW M3 models. See vehicle applications link for details.
The K&N 57-1003 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some BMW M3 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your M3’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-1003 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screwdriver, socket set and an Allen wrench. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

This M roadster I have is a rocket by itself. Then I added this air filter system. It is like it added a booster. Just wonderful products. Thanks so much. This is actually the 4th K&N air filter I have purchased. I wish you continued success.
