Details
P08 F1-85 - Maximum Airflow. Racing Performance.
Sprint Filter P08 F1-85 is an ultra-high-performance air filter developed for demanding racing applications, including MotoGP and Superbike competition.
Engineered to deliver exceptional airflow with effective filtration, P08 F1-85 represents Sprint Filter's most airflow-oriented polyester filtering technology. Although primarily designed for racing, it can also be used in suitable road applications.
Filtration & Performance
P08 F1-85 features an advanced polyester filtering media with a 22-micron fiber diameter and a filtration rating of 85 microns.
Its specialized weave delivers almost three times the airflow of P08, while maintaining a comparable filtration rating.
Developed using patented waterproof technology, P08 F1-85 combines extremely high permeability with protection against airborne contaminants.
Its characteristics make it particularly suitable for applications where maximizing intake airflow is a priority.
Easy Maintenance
P08 F1-85 requires minimal maintenance. Simply remove the filter from the airbox, clean it using compressed air and reinstall it.
No oiling, washing or special cleaning products are required under normal conditions, simplifying maintenance even in demanding racing environments.
Durability & Build Quality
Manufactured from high-quality synthetic polyester, P08 F1-85 is designed to maintain its structural integrity and filtering characteristics over time when properly maintained.
Developed through Sprint Filter's experience in professional motorsport, it combines advanced filtration engineering, high airflow capacity and reliable construction for demanding performance applications.
Fabrics of filters
The common performances air filters are composed of cotton yarn very large, the Sprint Filter polyester air filters instead consist of much smaller yarns and calibrated. Thanks to this type of construction the Sprint Filter polyester fabric allows a better filtration combined with a good air permeability, as shown by tests performed. It is necessary say that as regards the cotton fabric results obtained were not constant, this is due to the weak structure and mobile of cotton gauze, the following data are, however, best obtained. With respect to the polyester fabric data have remained constant and precise.

Air permeability
The uniform and compact polyester filtering element consists of a thin filament of fabric, forming a mesh of several dozen microns, capable of trapping all significant particles and ensuring a very high air flow rate. Our polyester air filter guarantees a very high air flow that neither cotton filters nor OEM paper filters can achieve. Remember this simple equation: More Air = More Power!
Efficiency filtration
The Sprint Filter polyester air filters retain 93.13% of 100 μ particles (Sprint Filter P08 air filter) - 91.8% of 37 μ particles (Sprint Filter P037 air filter) - 95.22% of 100 μ particles (Sprint Filter P08F1-85 air filter) versus the 76.42% of a common 4-layer oil-soaked cotton air filter
Because of its uniform structure, the Sprint Filter air filter ensures less air flow disturbance, also thanks to the exclusive and patented filtering material in single-layer polyester.
The realization
Sprint Filter creates over 65 years innovative products made with the most sophisticated and technologically advanced materials: from aluminum, steel, and then move on to materials in polyurethane foams to get to plastics all kinds of fine carbon and kevlar. The entire process of manufacturing our products is done internally with sophisticated equipment design and production: designed with advanced three-dimensional cad-cam our filters and extraction systems are built using molds developed with numerical control machines and realization fine with modern machinery for molding plastics and dispensing of polyurethane.
