Sprint Filter P08 Air Filter Aprilia RS 660 (2020-2026) PM176S

Sixty-five years of motorsport heritage and a podium-tested filtration philosophy are distilled into the Sprint Filter P08 for the Aprilia RS 660. Engineered in precision-woven polyester and shaped to drop straight into the OEM airbox, it is one of those rare upgrades that improves both engine protection and outright performance in a single fitment.

Key Features

• Exceptional airflow through an open polyester weave that raises the volume of filtered air reaching the throttle bodies, freeing up power on both road and track.
• Filtration rated to 80 microns, catching damaging particles before they can reach piston rings, bores and valve seats.
• Maintenance is a matter of minutes — compressed air through the element removes dust and debris; no oils, sprays or specialist kits required.
• Dimensionally stable polyester construction holds its shape service after service, resisting the deformation that degrades filtration efficiency in lesser filters.
• Proven at the highest level: Sprint Filter supplies teams competing in MotoGP and World Superbike Championship, bringing race-developed filtration to road-going machines.
• Direct OEM replacement geometry — remove the stock filter, fit the P08, close the airbox. No cutting, drilling or adapter plates.

Design, Finish and Heritage

Sprint Filter was founded in Italy and has spent more than six decades refining the art of high-flow air filtration for competition machinery. The P08 element carries that lineage visually as well as functionally: the distinctive woven polyester medium is a recognisable mark of a filter designed in a motorsport environment rather than adapted from automotive catalogues. Its clean, precise geometry reflects manufacturing tolerances developed for race-prep workshops where fitment accuracy is non-negotiable.

For RS 660 owners, that heritage matters. The parallel-twin architecture of the RS 660 is inherently sensitive to induction restrictions, and a filter that delivers a clean, consistent airflow signal to the fuel injection system allows the ECU to work with accurate data throughout the rev range. The P08 addresses this directly, making it a meaningful upgrade whether the bike lives on B-roads or sees regular track days.

Road and Track Use

The P08 is equally at home in both environments. On the road, improved filtration efficiency means the engine breathes cleaner air over a longer service interval without the progressive restriction that builds up in paper elements. On track, where induction demand spikes repeatedly and sustained high-rpm running is the norm, the high-flow weave ensures the airbox never becomes the limiting factor in the intake system. The dry polyester medium also means there is no risk of oil contamination reaching the intake sensors — a known issue with oiled cotton-gauze alternatives.

Fitment and Compatibility
