DescriptionThe whole story▼
When every lap counts and the engine is running at its absolute limit, standard filtration simply is not enough. The K&N KN-303 Racing Oil Filter is engineered specifically for competition use on the Kawasaki ZX-10 R and ZX-10 RR, delivering a higher flow rate and superior filtration than OEM units across the full 2006-2026 model range.
Key Features
- 17 mm hex fitting allows fast, tool-free removal with any standard spanner — no filter wrench required in the pit lane.
- Hex boss drilled for safety wire, meeting the lock-wiring requirements enforced at most race circuits.
- Pre-lubricated O-ring accelerates installation and ensures a leak-free seal from the first moment.
- Anti-drain-back valve keeps the filter primed between sessions, eliminating dry starts and protecting the engine on cold ignition.
- New overpressure relief valve maintains consistent oil pressure and prevents damaging pressure spikes under sustained high-rpm loads.
- Housing walls are 50% thicker than standard filters, reinforced baseplate with a double-rolled seam — built to withstand extreme oil pressures without distortion.
- Compatible with the latest fully synthetic racing oils and race-grade fuels.
Built for the Track, Proven Under Pressure
The KN-303 is not a road filter with a motorsport badge. K&N developed this unit from the ground up for racing applications, where oil temperatures spike, pressure fluctuates dramatically through corners and the filter must perform without compromise for an entire race distance. The reinforced steel canister and double-rolled baseplate seal resist the kind of thermal and mechanical stress that would degrade a conventional filter, while the high flow rate ensures the ZX-10 R's engine receives adequate lubrication even at maximum rpm.
Fitment & Compatibility
The K&N KN-303 is a direct-fit racing oil filter for the following Kawasaki models:
- Kawasaki ZX-10 R — all variants, model years 2006 to 2026
- Kawasaki ZX-10 RR — all variants, model years 2006 to 2026
