Sprint Filter P08F1-85 Air Filter – Aprilia RSV4 / RF / RR / 1100 Factory (2015-2026) PM147S_F1-85

The Sprint Filter P08F1-85 is the race-bred air filter trusted by factory MotoGP and World Superbike teams — and now available as a direct-fit replacement for the Aprilia RSV4, RSV4 RF, RSV4 RR and RSV4 1100 Factory (2015-2026). Delivering up to three times the airflow of the standard P08 filter, the P08F1-85 extracts every last horsepower your V4 can produce while maintaining filtration efficiency that meets the demands of both the circuit and the road.

Key Features

• Triple airflow output: up to three times the throughput of the standard Sprint Filter P08, unlocking the full performance potential of the Aprilia RSV4 platform.
• Precision polyester filtration: a purpose-engineered mesh with a wire diameter of just 22 microns captures particles up to 85 microns in size — the highest permeability of any filter in its class without sacrificing protection.
• World's only waterproof performance filter: a unique patented construction makes the P08F1-85 resistant to water ingress, maintaining consistent airflow even in wet or extreme conditions.
• Near-zero maintenance: clean with compressed air alone — no washing, no specialist cleaning fluids, no drying time. A genuine time and cost saving over traditional oiled-foam filters.
• Exceptional durability: the high-grade polyester medium retains its shape and filtration performance under sustained high-load use, with no measurable degradation or structural breakdown over time.
• Proven race pedigree: backed by over 65 years of filter manufacturing and active deployment in MotoGP, Moto3 and World Superbike competition.

Race Performance on the Road

Developed specifically for road racing applications, the P08F1-85 sits at the top of the Sprint Filter product hierarchy. The F1-85 designation refers to the 85-micron filtration grade — a specification chosen to maximise airflow at the expense of only marginal additional particle passage compared to finer grades. For track day riders and those running modified or tuned RSV4 engines, the gains in top-end breathing are tangible. The filter slots directly into the standard airbox without modification, so mapping and fuelling adjustments can be made to take full advantage of the increased charge volume.

Engineering & Construction

Sprint Filter manufactures the P08F1-85 from a monofilament polyester weave with a precisely controlled 22-micron wire diameter. Unlike traditional paper or oiled-foam elements, the polyester mesh does not absorb moisture, contract when wet, or require periodic re-oiling. The patented waterproofing technology ensures that the filter geometry remains stable regardless of ambient conditions — an important characteristic when the RSV4's airbox is subjected to rain, spray or pressure washing. The rigid frame holds the medium taut under the pressure differential created at high engine speeds, preventing bypass and ensuring every cubic centimetre of air is filtered before it reaches the throttle bodies.

Fitment & Compatibility

The Sprint Filter PM147S_F1-85 is a direct OEM-replacement air filter designed to fit the following Aprilia models:

• Aprilia RSV4 (2015-2026)
• Aprilia RSV4 RF (2015-2026)
• Aprilia RSV4 RR (2015-2026)
• Aprilia RSV4 1100 Factory (2015-2026)

No airbox modification is required. Fitment uses the original mounting points and sealing surfaces for a secure, rattle-free installation.
