DescriptionThe whole story▼
Engineered for riders who demand the absolute most from their Yamaha YZF-R6 RJ27, the Sprint Filter P08F1-85 delivers a genuine, measurable improvement in engine breathing with a fitment so precise it slots in as naturally as the original — making it just as comfortable to live with every single day as it is rewarding on a track day.
Key Features
- Nearly triple the airflow of the standard P08 filter, translating to a noticeable boost in throttle response and top-end pull without sacrificing filtration quality.
- Patented polyester weave with threads from 22 µm — retaining 95.22 % of 100-micron particles in the manufacturer's test — keeps abrasive particles out of your engine while maintaining outstanding permeability.
- Patented waterproof construction allows full confidence in wet commutes, touring in changeable weather, and damp track conditions alike.
- Virtually maintenance-free design: a blast of compressed air is all it takes to restore performance — no proprietary cleaning kits, no re-oiling, no fuss.
- Durable polyester medium retains its geometry and filtration efficiency year after year, resisting the degradation that affects foam and paper alternatives.
- Race-proven pedigree from Sprint Filter's involvement in MotoGP, Moto3 and World Superbike underpins the real-world reliability of every unit.
Built for All-Day Use, Ready for the Track
The P08F1-85 sits at the top of Sprint Filter's road and race hierarchy. The F1-85 polyester weave is the brand's highest-permeability fabric, yet it still holds back 95.22 % of 100-micron particles in Sprint Filter's test, more than the standard P08 at 93.13 % — a balance that took over 65 years of air filtration research and motorsport development to achieve. Whether you are threading through city traffic on a Tuesday morning or chasing lap times at the weekend, this filter works identically well in both environments without requiring any adjustment or additional preparation between the two.
Waterproof Technology You Can Rely On
Sprint Filter's patented waterproof technology sets the P08F1-85 apart from standard high-flow filters. The polyester medium does not absorb moisture, so a sudden downpour or a wet paddock will not compromise airflow or filtration efficiency. For R6 owners who ride in all conditions, this is a meaningful real-world advantage that foam filters simply cannot match.
