Sprint Filter P08 Air Filter for BMW M1000RR K66 (2021-2026) PM171S

Sixty-five years of motorsport filter engineering distilled into a single drop-in upgrade: the Sprint Filter P08 PM171S is the definitive air filter for the BMW M1000RR K66, engineered to deliver class-leading airflow and genuine engine protection in one beautifully constructed polyester unit. Whether you are chasing lap times or covering road miles, the P08 is the filter that works as hard as the M1000RR deserves.

Key Features

• Superior airflow: independently benchmarked to deliver the highest air throughput of any leading branded filter, directly maximising the M1000RR K66's power potential across the rev range.
• Precision filtration: a 70-micron wire-diameter polyester medium captures particles down to 80 microns, keeping abrasive debris away from the engine without strangling intake flow.
• Near-zero maintenance: clean with compressed air alone — no washing, no specialist cleaning fluid, no drying time. A significant practical and financial saving over oiled cotton alternatives.
• Proven dimensional stability: the polyester construction retains its exact shape and filtration geometry over years of use, with no degradation in performance or structural integrity.
• Motorsport heritage: Sprint Filter's technology has supported championship wins in MotoGP, Moto3 and World Superbike — the same design philosophy and manufacturing standards applied to every PM171S unit.

Design, Finish and Heritage

Sprint Filter was founded over 65 years ago with a singular focus: producing filters that outperform the OEM and every major aftermarket competitor. The P08 represents the marque's core "Standard" filter specification — a designation that carries considerably more weight than it might suggest. The polyester medium is the product of decades of motorsport refinement, chosen for its dimensional consistency, chemical resistance and the fact that it requires no oil treatment to achieve its rated filtration efficiency. The result is a filter that looks precise, fits precisely and performs precisely, session after session, year after year.

Road and Track Performance

The BMW M1000RR K66 is a machine that rewards marginal gains, and the intake side is one of the most accessible areas in which to find them. The P08 PM171S slots into the factory airbox without modification, immediately improving the volume and consistency of air reaching the throttle bodies. On road rides the benefit is felt as a crisper throttle response and a more linear power delivery; on track, where sustained high-rpm running demands both unrestricted flow and reliable filtration, the P08's combination of low restriction and 80-micron particle capture gives you the confidence to push without compromise.
