P08 Air Filter

The Sprint Filter PM160S represents an "AIR FILTER REVOLUTION," moving beyond traditional cotton gauze or oiled foam filters. Utilizing a unique P08 filtering membrane, this air filter is constructed from a precisely woven fabric of polyester threads with a 5-micron diameter. This innovative material offers superior airflow and filtration efficiency compared to conventional filters. Key to its performance is an optimized filtering surface area, achieved through a tighter pleat step of 8mm and a pleat height of 20mm. This design, significantly larger than standard filters, ensures consistent filtration across the entire RPM range. The P08 membrane provides airflow that is not comparable to cotton filters and remains constant over time. Maintenance is exceptionally straightforward. The Sprint Filter PM160S can be cleaned simply by using compressed air in the reverse direction of airflow to dislodge dust. This allows for immediate refitting without washing or drying. For more stubborn grime or oil, the filter can withstand degreasing agents and be cleaned with compressed air. Designed for both road and track applications, the PM160S is intended as a direct replacement for the original paper filter on stock motorcycles, without requiring ECU mapping modifications. It also offers potential performance advantages, with documented cases showing gains of up to 2.5 hp on a stock Honda CBR 1000 RR. For race use, the P08 filter has a racing origin, developed from SBK in 2009 with top teams, and is known to lean the air-fuel mixture by 1-5% while exhibiting significantly lower load losses than cotton or sponge filters.
