Sprint Filter P08F1-85 Air Filter Honda CBR 1000 RR SC77 (2017-2019) PM158S F1-85

Built to the exacting standards demanded by factory MotoGP and World SBK squads, the Sprint Filter P08F1-85 is the pinnacle of air filtration engineering for the Honda CBR 1000 RR SC77. Its precision-woven 22-micron polyester medium and patented waterproof construction set it apart from every competitor on the market — delivering triple the airflow of the standard P08 without compromising filtration integrity.

Key Features

• Triple airflow versus the standard Sprint Filter P08, translating directly into measurable gains in throttle response and top-end power on the CBR 1000 RR SC77.
• 22-micron polyester wire diameter filters particles up to 85 microns in size while maintaining the highest permeability of any production air filter.
• The world's only waterproof high-performance filter, engineered with a patented technology that keeps intake air clean even in wet or extreme racing conditions.
• Virtually maintenance-free — a blast of compressed air is all that is needed; no oils, no specialist cleaning kits, no downtime.
• Polyester construction retains its dimensional stability and filtration efficiency across years of hard use, track or road.
• Over 65 years of Sprint Filter heritage, proven at the highest levels of MotoGP, Moto3 and World Superbike competition.

Premium Construction

The defining characteristic of the P08F1-85 is the material itself. Sprint Filter's proprietary polyester weave achieves a wire diameter of just 22 microns — finer than many competing cotton-gauze products — yet the open structure permits an airflow volume three times greater than the standard P08. The result is an engine that breathes freely under full load without ingesting the fine debris that erodes bore surfaces over time.

Unlike foam or oiled-cotton filters that absorb water and restrict flow in wet conditions, the P08F1-85 uses a patented waterproofing process applied directly to the polyester medium. Water beads and drains away rather than saturating the filter matrix, so intake restriction does not spike mid-session when conditions change.

Track and Road Performance

Sprint Filter developed the F1-85 specification specifically to close the gap between maximum airflow and meaningful filtration — a compromise that the standard P08 resolves conservatively. The F1-85 variant shifts that balance firmly toward peak performance, making it the preferred choice for circuit days and spirited road riding on the CBR 1000 RR SC77 where every horsepower counts. Its near-zero maintenance requirement also makes it a practical upgrade for riders who want race-grade hardware without the workshop overhead.
