Sprint Filter P08 Air Filter for Road & Track – Yamaha XSR 900 GP/ GT (2024–2026) SM272S

The XSR 900 GP and the XSR 900 GT share a name, a platform and a part number, and share almost nothing about how they get ridden. One is a half-faired machine styled after a period racer and ridden accordingly, in short deliberate outings. The other carries a screen and luggage and is bought to cover distance. Sprint Filter lists a single element for both, the P08 SM272S, because the airbox behind the two of them is the same. What is not the same is the amount of air each one draws through it in a season, and that, not the badge on the tank, decides when the element needs attention.

Key Features

• Dry woven P08 polyester with no oil and no dressing applied to it, ever
• Threads of 22 microns in diameter and upwards, woven into a single dry layer
• Airflow rated at 5,050 litres per square metre per second, filtration at 80 microns
• About twice the filtering surface other performance filters offer
• In the standard airbox it takes the original's place: nothing modified, nothing remapped, homologation intact
• Washable and reusable, built for the machine's service life; two years of warranty from purchase

One part number, two different intervals

The interval printed in the manual is written for an average machine, and neither of these two is that average. A GP ridden a few thousand careful kilometres a year on clean roads will reach the mileage figure long after the calendar does. A GT that spends a summer on motorways and mountain passes will get there well before. With a disposable element the schedule is obeyed on faith in both directions, which means paying too early in one case and too late in the other. With the SM272S the decision moves back to the element: take it out, look at it, clean it if it needs it, refit it. That answer costs nothing, so it can be asked as often as the riding warrants.

An honest account of the difference

A drop-in filter does not make either version noticeably faster; the airbox, intake tract and fuelling map are unchanged, which is the point of a part built for the standard housing. What changes is that the intake restriction stops being a moving target. A loading paper cartridge gives up a little more every month and never says so. A dry polyester element is returned to its starting condition each time it is cleaned, which means the engine is breathing to the same specification in its fifth year as it did in its first, and no consumable has to be sourced to keep it that way.

Care and cleaning

Never dry it with heat and never near a flame; that instruction has no exception. Otherwise: compressed air from the clean side outwards, lukewarm water with a mild detergent when more is wanted, rinsed until the water runs clear, then open air until it is dry through. Refit it dry, with no oil used at any stage. The Sprint Filter maintenance sheet is in the Downloads tab.

Fitment & Compatibility

Made for the Yamaha XSR 900 GP and XSR 900 GT, 2024 to 2026. The same element covers four listings on this airbox, alongside the MT-09 / SP, the R9 and the Tracer 9 / GT; the full list is in the Fitment tab.
