Sprint Filter P08 Air Filter for Road & Track – Kawasaki Ninja 300 (2013–2017) PM95S

Kawasaki stopped building the Ninja 300 in 2017, and the Ninja 400 that replaced it in 2018 was a new motorcycle down to the airbox. That matters more than it sounds. From that model year on, nothing new was designed for this bike; every Ninja 300 still on the road is being kept going out of what already exists. So it is worth being plain first: a drop-in element does not make a standard motorcycle noticeably faster, and nobody should buy one expecting that. What the Sprint Filter P08 does here is quieter and fits the situation — it takes one line off the list of things this bike will keep needing.

Key Features

• Dry polyester cloth spun from threads of ø 22 microns upwards, with the weave itself rated at 80 microns
• Flow rate of 5,050 l/m²/sec — Sprint Filter's standard road and track medium
• Oil-free for its whole life, so nothing can migrate downstream onto a sensor or a throttle body
• Around twice the filtering area of other performance elements, folded into the same standard housing
• Sits in the series airbox in the original position; mapping and homologation stay untouched
• Cleaned and refitted instead of binned; built to last the life of the motorcycle and warranted for two years

The end of a line, not the start of one

This element covers a whole generation of small Kawasaki twins: the Ninja 250R from 2008, then the 300 from 2013 to 2017. Ten model years, one intake housing. The 2018 redesign broke that continuity — the Ninja 400 takes a different filter, so the element code is the reliable identifier here, not the family name on the tank. For an owner that cuts both ways. Supply for a discontinued model thins a little every year. But a part that is washed and put back stops being a supply question at all, and that answer will be no harder in 2032 than it was in 2019.

What a kept motorcycle asks for

Most of these bikes are well past their first owner and doing what the model was built for: licence years, commuting, riding schools, the occasional track day. That is a high-hours, modest-mileage life, and the odometer reports it badly. A filter ages by the volume of air drawn through it, and an hour in traffic moves far more of it than the trip counter implies. The honest benefit is a low intake restriction that stays low between services, rather than creeping upwards unseen as pressed paper loads.

Care and cleaning

Routine service on the PM95S is compressed air, aimed outwards from the clean face so the dirt leaves the way it arrived. A dusty summer or a salted winter earns more: lukewarm water with a mild washing-up detergent, rinsed until it runs clear, then left in open air until fully dry. Heat and flame ruin the weave, so neither comes near it. It goes back in dry and it goes back in bare — there is no oiling step in this element's life to get wrong. Sprint Filter's maintenance sheet sits in the Downloads tab.

Fitment & Compatibility

Made for the Kawasaki Ninja 300, 2013 to 2017. The same element serves three machines built around this airbox; the full list is in the Fitment tab.
