Sprint Filter P08F1-85 Air Filter for MV Agusta F3 675/800 (2012-2026) – CM135S F1-85

The Sprint Filter P08F1-85 is the race-derived air filter trusted by factory MotoGP and SBK teams — and it is a direct, no-compromise upgrade for the MV Agusta F3 675 and F3 800 (2012–2026). Built around Sprint Filter's patented single-layer polyester mesh, it meets the filtration standards demanded by professional competition while delivering almost three times the airflow of the standard P08 element. For riders who demand both engine safety and genuine performance gains, the P08F1-85 is the benchmark choice.

Key Features

• Race-proven filtration: the 22-micron wire-diameter polyester mesh captures particles up to 85 microns, matching the protection standard of the base P08 filter while operating at dramatically higher flow rates.
• Up to three times the airflow compared with the standard Sprint Filter P08, translating into measurable gains in throttle response and top-end power on the F3 platform.
• Patented waterproof construction keeps filtration performance consistent across rain, humidity and track conditions — no degradation in wet weather.
• Near-maintenance-free service life: simply blow clean with compressed air; no oiling, no chemical treatments, no drying time.
• Long-term dimensional stability — the polyester medium retains its shape and flow characteristics through extended use without measurable deterioration.
• Direct OEM-format fitment for the MV Agusta F3 675/800 (part number CM135S), requiring no modifications.

Technology & Build Quality

Sprint Filter developed the F1-85 specification for the demands of closed-circuit racing, where sustained wide-open-throttle running exposes any filtration compromise immediately. The single-layer polyester medium is woven to a consistent 22-micron wire diameter, creating a uniform mesh that is both finer and more open than foam or cotton gauze alternatives. The result is a filter that does not trade engine protection for airflow — the 85-micron filtration threshold remains intact regardless of how hard the engine is working.

The waterproofing technology is integrated at the weave level rather than applied as a coating, so it cannot wear off or wash out. This makes the P08F1-85 equally suited to a damp trackday morning and a dry summer road ride. When it does need attention, a burst of compressed air is sufficient; there is no oil to re-apply and no waiting for the element to dry before refitting.

Road & Track Use

On the MV Agusta F3 the intake airbox is a significant constraint on mid-range and top-end breathing. Fitting the P08F1-85 removes that restriction without altering the airbox geometry, making it a clean, reversible upgrade that complements ECU remaps, exhaust upgrades or standard-specification machines alike. Factory SBK teams running Sprint Filter elements have validated that the filtration level is sufficient for sustained competition use — confidence that translates directly to road and track riders who want maximum performance without gambling on engine wear.
