BMC Air Filter: Ref. 437/08
The original paper filter is convenient as a first fit, but once you've tried a washable cotton filter, it's hard to go back. The BMC ref. 437/08, made from multi-ply oiled cotton gauze, lets through more air than paper while trapping particles effectively. The result: better throttle response, an engine that breathes better, and no more disposable filters to buy.
Key Features
- Washable and reusable: unlimited service life with regular maintenance
- Higher airflow than the original paper filter
- Direct fit: no modification needed, 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 with the BMC cleaning kit (cleaner and re-oiling oil, sold separately). After washing, let air dry, then re-oil before refitting.
