Sprint Filter P14 Air Filter for Dusty Conditions – Yamaha XSR 900 GP/ GT (2024–2026) SM272P14

Sprint Filter offers this airbox in more than one material, and the difference is not one of grade. The P08 that covers most road and track use is a woven polyester fabric with a calibrated aperture, rated at 80 microns and 5,050 litres per square metre per second. The SM272P14 here is something else: a dry special nonwoven, a mat of fibres laid down rather than woven, filtering at 14 microns and flowing 1,800 litres. Choosing it for an XSR 900 GP or GT is not picking a better version of the same thing but a different construction, with a different balance between what it keeps out and what it lets through.

Key Features

• A dry special nonwoven mat rather than a woven fabric, filtering at 14 microns
• Rated airflow of 1,800 litres per square metre per second — the flow the finer structure costs, and it is real
• Dry throughout its life: no oil, no dressing, nothing that can be pulled downstream
• Sits in the series airbox of the XSR 900 GP and GT in the original element's place, with no housing work and no remap
• Brought back with an air line and refitted, rather than replaced as a consumable
• A two-year guarantee applies, starting on the purchase date

Woven and nonwoven are different tools

A woven fabric filters at a surface: threads cross at a set spacing, the openings between them are consistent, and particles are stopped where they meet that plane. A nonwoven has no such plane: the fibres are matted through the depth of the material, and air takes a winding path through the thickness rather than straight through a grid. That structure is how 14 microns becomes achievable in a housing this size, and it is also why the flow figure falls: a longer, more tortuous path is a slower one. They are two ways of building a filter for two different jobs.

The housing decides nothing about the material

The reason this is easy to live with: only the element changes. The airbox of the XSR 900 GP and the GT stays as it was, the intake tract, injection and mapping are untouched, and the bike remains what left the factory. So the material is decided on use, not on commitment. A GT loaded for distance on dusty summer roads has a clear case for 14 microns; a GP ridden briskly on clean tarmac is better served by the P08 and its 5,050 litres. Both parts occupy the same space in the same box.

Care and cleaning

Because a nonwoven carries its load through its thickness, the air line is doing more than dusting a surface: work it steadily over the whole element, always from the clean face outwards, so the dirt leaves the way it arrived. Water is the second stage when air is not enough — lukewarm, mild detergent, rinsed until it runs clear. Then open air and patience until the SM272P14 is dry right through. Heat and flames are excluded without exception; refit it only when dry. The maintenance sheet is in the Downloads tab.
