Sprint Filter P08 Air Filter for Road & Track – Kawasaki Z800 E ABS (2013–2015) OM33S

The letter in Z800 E ABS records a lower state of tune, not a different motorcycle: same four cylinders, same airbox, same panel in it. What the reduced output changes is not the hardware but the share of the ride spent asking the engine for everything it has — and that share decides whether the air filter is doing anything at all. Below a wide throttle the butterflies dominate the intake and the element is a rounding error. The OM33S matters on the far side of that line, which this version of the Z800 crosses more often.

Key Features

• One dry layer of woven polyester — never oiled, at the factory or afterwards
• 80 microns at 5,050 l/m²/sec, the medium Sprint Filter specifies for road and track use
• Polyester thread from ø 22 microns up; the aperture belongs to the weave, not to pressed fibre
• Approximately twice the filtering surface of the usual performance element
• Sits in the untouched airbox where the paper panel sat — no modification, no remapping
• Built to last the life of the machine; two years of warranty from the date of purchase

Where a filter is in play at all

Intake restriction is not a constant tax. At part throttle the rider is deliberately choking the engine with a plate that is far more restrictive than anything else in the path, and the state of the element is irrelevant. Only with the throttle wide does the rest of the path — duct, box, panel — become a measurable share of what the engine has to pull against. A machine held below its potential reaches that condition in ordinary riding more often than the full-power version, so on an E the element's state is less of a theoretical matter. The logic runs both ways: full airflow more often also means the panel loads faster.

What that is worth, honestly

Not power. A drop-in element does not make a standard Z800 noticeably stronger, whichever state of tune it left the factory in. The claim here is narrower and easier to keep: a restriction that starts low and goes back to where it started after every clean, rather than one that only ever grows between purchases. On a bike past a decade old, that is the difference between an intake maintained on principle and one maintained when somebody remembers to order a part.

Care and cleaning

An air line does the job: hold it against the clean side of the OM33S and walk it across the panel so the dirt is pushed back out of the face that gathered it. If something remains, lukewarm water with a small amount of mild detergent will release it, followed by a rinse until nothing more comes away. Drying happens in moving air and takes as long as it takes — a heat gun, a radiator or a flame will destroy the polyester. The element goes back dry and bare, with nothing sprayed on it.

Fitment & Compatibility

Cut for the airbox of the Kawasaki Z800 E ABS built between 2013 and 2015. Ten machines share this panel, the Z750 family and the earlier Z1000 among them, so it stayed in production long after any one of them left it. The full list is in the Fitment tab.
