Sprint Filter P08F1-85 Air Filter for Yamaha YZF-R3 (2015-2025) – PM44S F1-85

When your Yamaha YZF-R3 demands the cleanest air path and the strongest engine protection in any condition, the Sprint Filter P08F1-85 delivers exactly that. Developed for riders who refuse to compromise between outright performance and reliable filtration, this race-proven unit replaces the standard element with a polyester filter medium engineered to nearly triple the airflow of a conventional P08 — without sacrificing the filtration integrity your engine depends on.

Key Features

• Near triple the airflow of the standard P08 filter medium, unlocking measurable gains in throttle response and top-end performance on road and track alike.
• Polyester filter medium with a wire diameter of just 22 microns captures contaminants up to 85 microns, keeping abrasive particles out of the combustion chamber through every ride.
• Patented waterproof technology ensures consistent filtration performance in wet weather — no degradation, no bypass, no compromise to engine protection.
• Virtually maintenance-free design: the element cleans out easily with compressed air, requiring no oil treatment and no messy cleaning kits.
• Race-grade polyester construction resists deformation and flow loss even under sustained high-rpm conditions, giving a service life that outlasts standard paper elements.
• Direct OEM replacement fitment for all Yamaha YZF-R3 model years from 2015 to 2025 — no modification required.

Engineered for Protection and Performance

The F1-85 designation in the Sprint Filter nomenclature signals a specific filtration grade: the medium intercepts particles at 85 microns while maintaining an airflow rate that a standard paper filter simply cannot match. The polyester weave achieves this balance through a tightly controlled wire diameter of 22 microns — fine enough to act as a genuine barrier against road grit and track debris, open enough to feed the YZF-R3's intake with a consistently dense charge of clean air.

Where conventional performance filters rely on oil-impregnated cotton gauze to trap particles, Sprint Filter's dry polyester medium requires no oiling at any point in its service life. This matters particularly on the YZF-R3 where the airbox is a sealed unit: a dry medium eliminates any risk of oil mist migrating into the intake tract or fouling sensors, keeping the fuelling map accurate and the engine clean throughout.

Waterproof Technology for All Conditions

Sprint Filter holds patents on its waterproofing process, and for good reason. Standard high-flow filters can allow water ingestion in heavy rain — a risk that rises sharply when the throttle is held open and intake vacuum is high. The P08F1-85's waterproof medium repels moisture at the filter surface, maintaining airflow while preventing any water from passing through. For a bike used on back roads in changeable weather or during endurance track days, that protection is not a luxury: it is a meaningful safety advantage.

Fitment and Compatibility

The Sprint Filter P08F1-85 is a direct-fit replacement air filter for the following:

• Yamaha YZF-R3 — all variants, model years 2015 to 2025

Sprint Filter part number: PM44S F1-85. No airbox modification, no additional hardware, and no tuning changes are required for fitment on standard road-spec or lightly modified machines.
