The Classic 500 and Thunderbird 500 are styled very differently, one a retro roadster, the other a cruiser, but they share the same 500cc air-cooled engine and airbox underneath, which is why BMC makes a single filter that fits both.
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
- Built using BMC's "Full Moulding" process: one-piece construction with no glued seams
