As with their 500cc siblings, the Classic 350 and Thunderbird 350 share the same 350cc engine and airbox despite their very different styling, so a single BMC filter fits both without modification.
Benefits of BMC Air Filter
- Improved airflow and throttle response
- Washable and reusable for the life of the vehicle
- Filtration rated to roughly 7 microns, tighter than a typical OEM paper element
