Product Description

The K&N BM-8518 is a high-flow, washable and reusable panel air filter engineered to replace the stock air-filter element on a range of modern BMW motorcycles - including F750GS, F850GS, F900R, and F900XR, among others. Its cotton-gauze, pleated media design significantly improves airflow compared to standard OEM paper filters, helping the engine breathe more freely for better throttle response and smoother operation - particularly under load or during spirited riding. The application-specific sealing bead ensures a precise, air-tight fit in the OEM air-box, eliminating the need for modifications when installed correctly.

Because BM-8518 is washable and reusable, it offers long-term value and lowers maintenance costs by eliminating frequent filter replacements. With periodic cleaning and re-oiling according to manufacturer guidelines, the filter can deliver reliable performance over many service intervals. It's especially appealing to riders who want enhanced engine breathing, consistent performance, and reduced waste without compromising filtration quality or air-box integrity.
