Sprint Filter P08F1-85 Air Filter – Yamaha YZF-R7 (2021-2026) CM148S

Born on the circuit and refined for the road, the Sprint Filter P08F1-85 is the performance air filter of choice for Yamaha YZF-R7 riders who refuse to leave horsepower on the table. Carrying the CM148S part reference and engineered to racing tolerances, the P08F1-85 delivers close to triple the airflow of the standard P08 filter while maintaining exceptional filtration efficiency — a genuine upgrade whether you are chasing lap times or simply want your R7 to breathe the way it was meant to.

Key Features

• Airflow approaching three times that of the standard P08 filter, unlocking the full intake potential of the YZF-R7 CP2 engine without sacrificing filtration quality.
• Precision polyester filter medium with a wire diameter of just 22 microns, capturing particles up to 85 microns while maintaining the highest possible air permeability.
• Patented waterproof construction makes the P08F1-85 genuinely all-weather capable — no performance drop when riding in wet or damp conditions.
• Maintenance-free in practical terms: a blast of compressed air is all that is needed to restore the filter, with no oiling treatments or liquid washing required.
• Polyester medium retains its filtration and flow characteristics even under prolonged high-intensity use, delivering a service life that justifies the investment.
• Direct OEM-replacement fitment for the Yamaha YZF-R7 — no modifications, no adapters.

Track-Bred Engineering for the Street

Sprint Filter developed the F1-85 specification specifically around the demands of circuit racing, where maximising intake airflow translates directly into measurable power gains and sharper throttle response. The polyester weave at 85-micron filtration sits at the optimal crossover point: fine enough to protect precision engine internals from abrasive particles, yet open enough to drop intake restriction to near-zero compared with a standard paper filter. On the YZF-R7 — a motorcycle already praised for its linear CP2 power delivery — reducing intake restriction lets the engine's true character come forward, with a stronger mid-range pull and a more willing top-end response.

Simplified Servicing, No Compromise

Unlike oiled cotton-gauze alternatives, the P08F1-85 requires no re-oiling between service intervals. Compressed air directed through the filter medium dislodges accumulated dirt and fully restores airflow in minutes. There are no specialist cleaning products to stock, no mess, and no risk of over-oiling contaminating the airbox sensors. For club racers managing filters across a race weekend, or road riders who simply want hassle-free ownership, this is a significant practical advantage.
