Sprint Filter P08 Air Filter for Road & Track – Kawasaki EN 650 Vulcan / S (2015–2026) PM163S

A cruiser spends a disproportionate amount of its life stationary with the engine running. Traffic lights, town centres, a slow ride-in on a summer evening — situations where there is no meaningful airflow over the machine and the heat the engine makes stays close to it. Everything in that space gets warmer than it would at speed, filter oil included, which is a good reason not to have any. The Sprint Filter P08 PM163S filters by woven structure rather than by tack: the polyester is dry, has never been oiled, and there is nothing in it that can thin, creep or find its way onto the throttle bodies when the bike is sitting in traffic on a hot day.

Key Features

• Filters by its woven structure rather than by tack: the polyester is dry, has never been oiled, and can leave nothing behind on the sensors or the throttle bodies
• Polyester thread from ø 22 microns, given its aperture by the weave and not by pressed pulp
• Roughly double the filtering surface you get from other performance filters
• Drops into the standard airbox with no modification, no remap and no change to homologation
• Washed rather than replaced; compressed air is the normal service
• The warranty is two years, running from the date of purchase

Low revs are where this engine is judged

The Vulcan is ridden in the bottom half of the rev range almost all of the time. That is not the part of the map where peak figures live, and no plug-in air filter is going to give a standard motorcycle a power it did not leave the factory with. What restriction does affect at low revs is the immediacy of the response — whether pulling away from a junction feels crisp or slightly muffled. Keeping intake restriction low and stable simply keeps that behaviour the way the factory calibrated it, service after service, instead of letting it drift as a paper element loads.

Two versions, one airbox, eleven years

The Vulcan and Vulcan S share their intake, and this one part number covers the range from 2015 through 2026. That has a practical consequence for anyone keeping the bike a long time: the element is supported by the whole 650 twin family rather than by a single model line, so it stays a current part. It is designed to last the life of the motorcycle, carries two years of warranty from purchase, and is

Care and cleaning

Everyday cleaning is compressed air, from the clean side and blown outwards. When more than that is called for, lukewarm water with a mild detergent does it, rinsed until the water runs clear. The element has to dry right through in open air — never with heat, never with a flame — and it is refitted dry. Nothing is oiled, before or after.

Fitment & Compatibility

Made for the Kawasaki EN 650 Vulcan and Vulcan S, 2015 to 2026. The same PM163S element serves five machines built around this airbox; the complete list is in the Fitment tab.
