Product Description

The K&N BM-1205 is a performance-oriented replacement air filter designed for several BMW K-series motorcycles (K1200 and K1300). Compared to stock paper filters, this filter's pleated cotton-gauze media and tapered conical shape allow significantly improved airflow into the engine, enhancing throttle response, smoother power delivery and potential gains under load - while still maintaining excellent filtration and engine protection. Because it is washable and reusable with a large filtration surface, the BM-1205 offers long service intervals and reduced maintenance costs over time.

Installation is simple: the filter is designed with an application-specific base seal to fit the OEM airbox, and it comes pre-oiled and ready to install. The included sealing grease helps ensure a tight seal to prevent unfiltered air ingress. For bikes with twin-airbox setups (common on some K-series variants), you may require two BM-1205 filters - verify your airbox configuration before purchase.
