Sprint Filter P08F1-85 Air Filter – Suzuki GSX-R 1000 (2009–2016) PM91S

Engineered from premium polyester filtration media and backed by over 65 years of motorsport development, the Sprint Filter P08F1-85 is the definitive high-performance air filter for the Suzuki GSX-R 1000 (2009–2016). Where lesser filters force a compromise between airflow and filtration efficiency, the F1-85 specification delivers triple the airflow of the standard P08 while still capturing particles down to 85 microns — a combination proven at MotoGP and World SBK level.

Key Features

• Triple the airflow of the standard Sprint Filter P08, unlocking measurable power gains across the rev range without sacrificing engine protection.
• 85-micron filtration threshold keeps fine road and track debris out of the engine while maintaining the highest air permeability of any leading filter brand.
• Patented waterproof polyester construction performs reliably in rain, humidity, dust and the harshest track conditions — no oiling required, no degradation over time.
• Virtually maintenance-free: a blast of compressed air is all that is needed to restore the filter to full performance, saving time and ongoing running costs.
• Durable polyester media retains its structural integrity and filtration performance across years of hard use, unlike paper or foam alternatives.
• Direct OEM replacement fitment for the GSX-R 1000 (2009–2016) — drop-in installation, no modifications needed.

Build Quality and Materials

Sprint Filter's choice of polyester as the filtration medium is central to the P08F1-85's character. Unlike oiled cotton gauze or traditional paper elements, the polyester weave is inherently hydrophobic — water passes over the surface rather than saturating the media. This makes the filter equally at home on a wet British B-road or a dry circuit. The material also holds its geometry under sustained high-velocity airflow, meaning the filter you install today will flow just as freely a decade from now provided it is cleaned periodically.

The F1-85 designation signifies the racing-grade variant of Sprint Filter's P08 platform. With a filtration rating of 85 microns and a flow rate three times greater than the baseline P08, it represents the most aggressive specification in the range — a direct result of knowledge accumulated through continuous involvement in the world's top two road-racing championships.

Performance on Road and Track

For Suzuki GSX-R 1000 riders who push their machines in both environments, the P08F1-85 offers a genuine performance upgrade. The dramatically increased airflow allows the fuel injection system to breathe more freely, which translates to sharper throttle response and stronger top-end pull. At the same time, the 85-micron filtration barrier keeps ingested grit and debris from reaching the engine — a balance that took Sprint Filter's engineers more than six decades to perfect.

Fitment and Compatibility

The Sprint Filter P08F1-85 (part number PM91S) is a direct-fit replacement for the following model:

• Suzuki GSX-R 1000 — model years 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016
