Sprint Filter P08 Air Filter for Road & Track – Yamaha MT-03 (2015–2026) PM44S

A large share of MT-03s never belong to the person riding them. It is one of the standard A2 machines of riding schools and rental fleets, and a bike in that service is looked after by an operator for whom every consumable is multiplied by the number of machines in the yard. A disposable air filter is a line that repeats per machine, per service, for as long as the fleet exists. The Sprint Filter P08 PM44S is bought once per motorcycle instead: dry woven polyester, cleaned with the compressed air already on the wall, and built to last the life of the machine.

Key Features

• 80 microns of filtration with 5,050 litres per square metre per second of flow
• The P08 medium is dry polyester, never oiled, so no film reaches the intake sensors
• Twice the filtering area, near enough, of other performance filters
• Replaces the original in the standard airbox: nothing modified, nothing remapped, homologation intact
• Washable and reusable, built to stay with the motorcycle for life
• Warranty of two years from the day it was bought

What fleet duty does to an intake

Training work is slow, repetitive and close to the ground: first-gear manoeuvring, clutch and brake dust, and an apron stirred up all day by the machines using it. None of that is what a service schedule was written around. A washable element lets an operator restore the intake when the conditions warrant it rather than when a part has arrived — the job costs labour and nothing else.

Dry, because oil is one more thing to stock and dose

Oiled cotton gauze needs its oil renewed correctly after every clean. Across a yard of motorcycles that is a stock item, a procedure and a way to get it wrong; too much, and the surplus sits where the engine measures its air. The P08 has no such step: woven polyester spun from threads of 22 microns and upwards, used dry and regenerated with an air line. Sprint Filter's own comparison puts a four-layer oiled cotton filter at 76.42 per cent retention of 100-micron test particles against 93.13 per cent for the dry P08. Finer media exist where the work justifies them — P037 at 37 microns, P14 at 14 — but each step finer costs flow: 5,050 litres per square metre per second against 4,500 and 1,800. Finer holds more and passes less; it is a trade, not a ranking. No filter in a standard airbox adds power. What this one adds is a low intake resistance that stays where it was put.

Care and cleaning

Nothing gets oiled here, and nothing gets dried with heat: no hot air, no flame. The regular service is compressed air from the clean side outwards. Where that leaves dirt behind, lukewarm water and a mild detergent lift it, rinsed until the water runs clear. It then sits in open air until dry through, and is refitted dry.

Fitment & Compatibility

Made for the Yamaha MT-03, 2015 to 2026, and a direct replacement in the standard airbox. The same PM44S element serves four machines built around this airbox: the MT-03, the YZF-R25, the YZF-R3 and the SR 400; the full list is in the Fitment tab.
