K&N 10-11 BMW S1000RR 990 Race Specific Air Filter

K&N Engineering is well-known for its high-flow air filters, and this BM-1010R race-specific air filter is built with that reputation in mind. This filter is designed for closed-course competition use only, meaning it's intended for track days and racing where maximum airflow is critical. It features just two layers of K&N's signature cotton gauze, which results in even lower air restriction compared to their standard replacement filters for street vehicles.

Because this filter allows for significantly more air into the engine, you'll need to make fuel management modifications to ensure your engine runs correctly and safely. This isn't a simple bolt-on part for a street bike; it's for dedicated racing setups where performance gains in horsepower and acceleration are the primary goal. Despite its performance focus, it's still washable and reusable, so you can clean and re-oil it for continued use over multiple seasons.

This filter fits a range of BMW models, including the S1000RR, S1000R, and HP4. Remember, this is strictly for competition use, not for street riding.
