Sprint Filter P08 F1-85 air filter PM171S F1-85

Sprint Filter P08 F1-85 is the ultimate performance air filter from Sprint Filter, developed over many years and used by Factory MotoGP and SBK Racing Teams.

Independent testing by the University of Wales Trinity St David showed that Sprint Filter's P08 polyester filter provides the best airflow among leading brands, including race filters. The P08F1-85, however, offers nearly three times the airflow of the P08 while maintaining similar filtration performance, making it suitable for both moderate road use and racing.

The P08F1-85 uses a special polyester material with a 22-micron wire diameter. Designed for road racing, it features patented waterproof technology, making it unique in its class. Its weave pattern filters debris as small as 85 microns and offers the highest permeability among air filters. This increased airflow helps maximize your bike’s power potential while ensuring excellent filtration protection. It’s suitable for racing and can be used on modern production road vehicles without needing carburation adjustments or additional control units.

Virtually Maintenance-Free

To clean the P08F1-85, simply remove it from the airbox, blow it clean with compressed air, and reinsert it. No washing, special cleaners, or oil treatments are needed, saving you time and money.

With proper care, the P08F1-85's polyester material will not deteriorate or lose performance over your bike’s lifetime.
