The K&N 63-1116 Air Intake fits some BMW M3 models. See vehicle applications link for details.
The K&N 63-1116 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on specific BMW M3 models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your 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 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original 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 crank case vent hose. 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 your vehicle’s existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches.

Spot on service and great fit. Just waiting for the exhaust to be made, then onto the dump to see the results.

When I first open the box I thought I had made a mistake by taking on this project. After looking at the instructions I quickly realized that this was going to be a piece of cake. The instructions are very clear and simple to understand. After gathering the needed tools I dove into the installation with both feet. Approximately 1.5 hours later, with a short break for a cold soda, it was complete. I reattached the battery and took my M3 for a quick drive. I instantly noticed the improved throttle response and throaty sound to the engine. After 2 weeks, I've noticed the increased performance and fuel mileage slightly increase. If you own a 2008-2013 e9x M3 and you don't make this modification, YOU ARE A FOOL. This is truly valuable bang for the buck.

You can feel the added horsepower from the get go. I also love the sound that is coming from the engine that was muffled by the old air filter box.

Noticeable improvement in the middle rev range, both in terms of immediate response and thrust. Also, the car sounds incredibly better, it seems you drive a big motorbike, also in the mid-range. If you're not considering a sport exhaust, this will be make the job as well. Overall a great addition to the car.
