BMC Twin Filter FMSA47-64-45

The BMC FMSA47-64-45 air filter is the high-performance Standard version direct replacement filter. BMC's iconic red filter for everyday use: more airflow, better filtration, and a longer lifespan compared to the original paper filter.

• Increased airflow to the engine: BMC cotton gauze has wider weaves than OEM paper, allowing for greater flow without sacrificing filtration.
• 97.5% filtration efficiency — ISO5011 standard: blocks all impurities larger than 7 microns, providing superior protection to the original filter.
• Larger filtration area: maximum permeability and airflow compared to standard panel filters.
• Washable and reusable: regenerate with the official BMC kit every 20,000–25,000 km, lasting the lifetime of the motorcycle.
• The choice of champions: BMC supplies the most important teams in Formula 1, MotoGP, and WorldSBK.

Direct installation in the original airbox without any modifications. Check exact compatibility with your motorcycle using the OEM reference.
