BMC Air Filter: Part No. 206-4206

The original paper filter is convenient as original equipment, but once you've tried a washable cotton filter, it's hard to go back. The BMC part no. 206-4206, made of multi-ply oiled cotton gauze, lets through more air than paper while still trapping particles effectively. The result: sharper throttle response, an engine that breathes better, and no more buying disposable filters.

Key features

  • Washable and reusable: unlimited service life with regular maintenance
  • Higher airflow than the original paper filter
  • Direct fit: no modification, plug-and-play replacement
  • Efficient filtration: multi-ply oiled cotton gauze
  • Warranty: 2 years

Filter maintenance

Cleaning recommended every 15,000 to 20,000 km using the BMC maintenance kit (cleaner + re-oiling oil, sold separately). After washing, let air dry, then re-oil before reinstalling.
