DescriptionThe whole story▼
The BMC replacement air filter FM465/04 is a direct, drop-in upgrade for the Triumph Daytona 675 and Daytona 675 R (2006–2012) that delivers the kind of unrestricted airflow a triple-cylinder engine deserves. Developed from race-proven technology, it replaces the restrictive OEM paper element with a washable, reusable cotton unit that keeps the motor breathing freely ride after ride, season after season.
Key Features
- Four-layer oiled cotton gauze construction maximises airflow while maintaining genuinely effective filtration — more air in, more performance out.
- Low-tack oil treatment across the cotton layers captures fine particles and contaminants without creating the pressure drop associated with denser filter media.
- Aluminium mesh backing shields the cotton from petrol vapour and oxidation, preserving filter integrity and extending service life well beyond that of a disposable paper element.
- Rubber frame surround absorbs vibration and prevents cracking, ensuring a consistent, leak-free seal against the airbox every time.
- Washable and fully reusable — clean, re-oil and refit rather than replace, saving cost across the life of the motorcycle.
- Tested to international filtration standards, giving confidence that performance gains do not come at the expense of engine protection.
All-Day Performance, Every Day
Where a standard paper filter gradually loses efficiency as it loads with dirt, the FM465/04's four-layer cotton medium continues to flow freely and filters more effectively over extended intervals. The result is a more consistent throttle response and a stronger mid-range pull that you can feel on the daily commute just as much as on a Sunday blast through the hills. Because the filter is reusable, it suits riders who cover high annual mileages and want a filtration solution that keeps pace with their commitment to the machine.
Build Quality You Can Trust
BMC manufactures each filter to exacting tolerances. The aluminium mesh provides structural rigidity and acts as a barrier against the corrosive effects of petrol vapour, so the cotton retains its shape and oil retention properties over many cleaning cycles. The rubber perimeter frame compresses evenly against the airbox seating face, eliminating any risk of unfiltered air bypassing the element — a critical detail for an engine running as close to its limits as the Daytona 675's 675 cc inline triple.
