Sprint Filter P14 Air Filter for Dusty Conditions – Yamaha R9 (2025–2026) SM272P14

A flow rating is a ceiling, and the question worth asking on a supersport is how often the engine goes looking for it. The Sprint Filter P14 SM272P14 is the fine-filtration element for the R9's standard airbox: a dry special nonwoven holding back down to 14 microns, against the 80 microns of the P08 that normally serves this housing. The retention is not free. Rated airflow falls from 5,050 to 1,800 litres per square metre per second, and on a machine built to be held wide open that deserves an honest hearing first.

Key Features

• 14 microns of filtration from a dry nonwoven medium, made for air that carries dust
• 1,800 litres per square metre per second of rated airflow — the price of the finer mat, stated rather than hidden
• Completely dry in service: no oil goes near it, so nothing can travel downstream onto the sensors
• Built for the R9's series airbox and fitted in the original element's place, without work on the housing and without remapping
• Regenerated with compressed air and used again instead of replaced at every service, for the life of the bike
• Two years of guarantee from the date on the invoice

How much of a ride happens at full flow

On a circuit, a lap of any length contains long stretches at maximum throttle, and across a session those add up to minutes rather than seconds. That is the case where the P08 is the better choice for an R9: 80 microns and 5,050 litres give the engine the headroom it is genuinely being asked for, and there is little sense in trading away something the bike is using. On the road the arithmetic turns around. Even ridden briskly, a road-registered R9 reaches the throttle stop in short bursts between corners and limits, and otherwise sits well inside what either medium can pass.

Choosing without guessing

The useful test is not how fast the bike is but how the year is spent on it. If track days are a fixed part of the season, buy the P08 and keep this page for reference. If the R9 is a road bike — summer distance, mountain roads still carrying winter grit, a gravel car park at the end of a good route — then 14 microns holds back a fraction a coarser weave passes, and the flow given up sits above the range that riding occupies. Nothing is permanent either: the airbox is untouched in both cases, so the medium can be reconsidered at any service.

Care and cleaning

Servicing is dry from start to finish, because nothing on the SM272P14 is ever oiled. Blow it through with compressed air against the direction of normal flow, entering from the clean face, covering the full area. If air is not enough, warm water with a mild detergent will do it, rinsed until what runs off is clear. Drying happens in the open, all the way through, with no heat source and no flame near it; it goes back only once properly dry. Sprint Filter's maintenance sheet sits in the Downloads tab.

Fitment & Compatibility

For the Yamaha R9, 2025 to 2026. The same element serves four listings on this airbox, alongside the MT-09 / SP, the Tracer 9 / GT and the XSR 900 GP/ GT; the complete list is in the Fitment tab.
