Efficient air supply and sustainable performance for the F 900 / 850 / 750.

The K&N high-performance air filter for the F models has been developed to significantly optimise airflow to the engine while ensuring reliable filtration. The multi-layer, oiled cotton gauze enables an especially large filtration area, effectively trapping dirt particles while maintaining a high airflow rate.

Improved airflow allows more oxygen to reach the engine, which can enhance combustion efficiency and positively impact performance, throttle response and torque. At the same time, the filter stands out for its durability: instead of requiring regular replacement, it can simply be cleaned and reused – saving costs while also reducing environmental impact.

Thanks to its precise fit, the filter integrates seamlessly into the standard air filter housing without requiring any modifications to the engine management system. The pleated filter medium also ensures long service intervals and consistently high performance – even under demanding conditions.

Overall, the K&N air filter offers an ideal combination of performance, efficiency and sustainability – perfectly tailored to the requirements of modern BMW twin-cylinder engines.
