Sprint Filter P08 Air Filter for Road & Track – Kawasaki Ninja 1100 SX (2025–2026) PM111S

The displacement went up and the part number did not change. One element, PM111S, covers both the 1,000 cc sport-tourer and the 1,100 that replaced it, which tells you something about how the intake was sized in the first place: with enough margin that a larger engine could be dropped into the same airbox without the filter becoming the limit. That margin is worth protecting. The Sprint Filter P08 is a woven polyester element that starts at a low restriction and is washed rather than replaced, so the headroom the engineers left is still there at the fourth service instead of having been eaten quietly by a loading paper element.

Key Features

• The standard airbox keeps its shape — the element drops in, with no modification, no remap and no change to homologation
• Filtering surface roughly double what other performance filters bring
• Polyester thread from ø 22 microns, calibrated by the weave rather than pressed from pulp
• Dry medium, never oiled — there is no film that could travel as far as the sensors or the throttle bodies
• Washable and reusable; an air line is the normal service
• The warranty covers two years from the date of purchase

A bigger engine in the same box

More displacement means more air per revolution through an intake path that was not enlarged to match. Nothing about that is a problem on a standard machine — the factory signed it off and the bike meets its homologation exactly as delivered — but it does mean the filter has slightly less spare capacity than it did on the smaller engine. A medium with roughly double the surface of other performance filters is the sensible response: the same road dust is distributed across more material, so the point at which loading begins to register arrives later.

New bike, first service pattern

On a machine this new the intake has no history yet, and the habits set in the first two years are the ones that stick. Choosing a washable element now means the airbox is opened on a schedule rather than when something feels wrong, and that each visit ends with the restriction back where it began. Sprint Filter design the P08 to last the life of the motorcycle and back it with two years of warranty from purchase — for an owner planning to keep the bike a long time, that is the last air filter decision the bike needs.

Care and cleaning

Dry service, start to finish. Compressed air from the clean side, blown outwards, does the regular work; a dirty spell earns lukewarm water with a mild detergent and a rinse until the water runs clear. The element then dries fully in air — never with heat, never with a flame — and is refitted dry. The polyester is never oiled. The Sprint Filter maintenance sheet is in the Downloads tab.

Fitment & Compatibility

Made for the Kawasaki Ninja 1100 SX, 2025 to 2026. The same PM111S element serves twelve machines built around this airbox, from the 2010 Z1000 to the current 1,100 cc models; the complete list is in the Fitment tab.
