Sprint Filter P08 Air Filter for Road & Track – Kawasaki Z1000 (2017–2025) PM111S

A big inline four does not sip at the airbox in separate gulps the way a single or a large twin does. Four intake events follow one another closely enough that the demand behind the filter is close to continuous, especially once the engine is spinning hard. That changes what restriction feels like. On a lumpy twin a tight filter shows up as a soggy edge to individual pulses; on the Z1000 it shows up as a flat, even tax across the whole rev range, the kind nobody notices arriving because nothing ever stumbles. The Sprint Filter P08 PM111S is aimed squarely at that quiet tax: a low starting restriction and, because the element is washed rather than replaced, a restriction that stays where it started between services.

Key Features

• Dry polyester, never oiled: nothing can be carried downstream onto sensors or throttle bodies
• The weave sets the aperture — polyester thread from ø 22 microns, rather than a sheet pressed from pulp
• Getting on for double the filtering surface of other performance filters
• Direct into the standard airbox, with no modification, no remap and no change to homologation
• Compressed air is the service; the element is washed and refitted rather than bought again
• Warranty: two years, measured from the purchase date

Continuous demand, continuous drag

Because the four cylinders overlap their demand, the airbox on this engine is rarely allowed to recover. Whatever pressure drop the element imposes is imposed nearly all of the time the throttle is open, and it grows as the medium loads. This is not a claim that a filter unlocks hidden horsepower — it does not, and a standard Z1000 will not suddenly feel like a different motorcycle. What it does mean is that a filter which loads slowly and can be returned to its original state is worth more on a four than the same part would be on an engine that only breathes hard occasionally.

Nine model years on one part number

This generation of Z1000 ran from 2017 to 2025, which is long enough that the second and third owners are now the ones paying the service bills. A consumable that is bought once and then cleaned changes that arithmetic. The P08 is built by Sprint Filter to last the life of the motorcycle, so the intake stops appearing on the shopping list altogether — the annual job becomes ten minutes with an air line rather than a call to see whether the element is still stocked.

Care and cleaning

Take it out, blow it through from the clean side with compressed air, put it back. That is the standard service. A deeper clean is lukewarm water and a mild detergent, rinsed until the water runs clear, after which the element dries fully in air — never with heat, never with a flame — and is refitted dry. There is no oiling step. The Sprint Filter maintenance sheet is in the Downloads tab.

Fitment & Compatibility

Made for the Kawasaki Z1000, 2017 to 2025. The same PM111S element covers twelve machines built around this airbox, including the 2010–2013 Z1000 and the Z1000SX variants; the complete list is in the Fitment tab.
