DescriptionThe whole story▼
Engineered in the same lineage as filters trusted at MotoGP and World SBK level, the Sprint Filter P08F1-85 brings race-proven filtration technology directly to the Triumph Daytona 675 and 675R. The F1-85 designation tells the story: a patented waterproof polyester construction that flows almost three times the air of a standard P08 filter while still capturing particles down to 85 microns — a combination that suits both spirited road riding and serious track days without compromise.
Key Features
- Nearly triple the airflow of the standard Sprint Filter P08, helping the Daytona 675 engine breathe freely and reach its performance potential
- Patented waterproof technology makes the filter suitable for all weather conditions, from damp morning commutes to full British summer riding
- Polyester filter medium traps particles down to 85 microns, providing genuine engine protection alongside the improved airflow
- Maintenance is straightforward: clean with compressed air alone — no aftermarket cleaning solutions or oil treatments required
- Durable polyester construction retains its shape, integrity and filtration efficiency over years of use without measurable degradation
- Race-validated pedigree — Sprint Filter's F1-85 technology has been used in MotoGP and World SBK, the most demanding filtration environments in motorsport
Design, Finish and Heritage
Sprint Filter has spent over 65 years refining air filtration for performance applications, and the P08F1-85 reflects that accumulated expertise in every detail. The distinctive polyester weave is precisely engineered rather than simply adapted from a generic format — the open structure is optimised to balance filtration efficiency against minimal restriction, which is exactly why top-level race programmes chose it. For Daytona 675 owners who appreciate the engineering heritage behind a component as much as its dyno output, the P08F1-85 sits at the intersection of proven race technology and everyday usability. Its clean, purposeful appearance is consistent with the Daytona's own sharply focused character.
Performance on Road and Track
Replacing the standard air filter with the P08F1-85 gives the inline three-cylinder engine in the Daytona 675 and 675R a less restricted intake path. On the road this translates to more responsive throttle pickup across the rev range, while on circuit the increased airflow supports the engine through repeated high-rpm runs where an underperforming filter would begin to limit power delivery. Because the filter requires no oiling, there is no risk of excess oil migrating onto the mass airflow sensor — a common concern with some competing products.
