Sprint Filter P08 F1-85 Air Filter for Racing – Kawasaki Eliminator (2024–2026) PM164S F1-85

Cruisers get modified more thoroughly than almost any other category, and the modifications tend to run in one direction: a freer exhaust, a reworked intake, and mapping to suit. A Kawasaki Eliminator built that way is no longer a standard motorcycle in the one respect that decides whether a high-flow element does anything — the engine is finally in a position to use air that arrives more easily. That is the case in which the P08 F1-85 belongs on this bike: 15,000 l/m²/sec of air flow against the standard P08's 5,050, bought with a filtration of 85 microns instead of 80.

Key Features

• Dry polyester, never oiled — nothing to migrate onto throttle bodies or sensors
• Two years of warranty; the element is designed to last the life of the motorcycle
• Racing medium at 15,000 l/m²/sec, the highest flow Sprint Filter offers
• Filtration to 85 microns — the wider aperture is the price of that flow
• Installs in the standard airbox with no modification and no remap
• Washable and reusable, cleaned with compressed air from the clean side

The airbox is worth keeping

The usual next step on a build like this is an open cone filter, and it is worth saying why an element inside the standard box is often the better one. An airbox does more than hold a filter: it silences intake noise, it presents the engine with air of a settled temperature and pressure rather than whatever is passing the frame, and it keeps water and road spray away from the intake. Replacing the fabric inside it keeps all of that and changes the one thing that was restricting flow. Removing the box gives up three functions to improve one.

And if the bike is standard

Then this is the wrong element, and there is no reason to dress that up. A standard Eliminator is not limited by its filter, cannot use the extra flow, and would simply be filtering more coarsely than before — on a machine ridden slowly in traffic, where the air is fine and constant. The standard P08 covers that use, and the P14 at 14 microns covers it better if the roads are dusty. The airbox takes any of the three, so the decision can be revisited whenever the build changes.

Care and cleaning

Compressed air, from the clean side and directed outwards, is the normal service, and the element is refitted dry afterwards. When it needs more, put it into lukewarm water with a mild detergent and rinse it until the water runs clear; what follows matters just as much, because the medium then has to dry fully in air, never with heat and never near a flame. No oil is applied at any point, which on a build with an open exhaust leaves one variable fewer between the air and the engine. The Sprint Filter maintenance sheet is in the Downloads tab.
