DescriptionThe whole story▼
Track regulations demand that every component on your Yamaha YZF-R3 meets a verifiable safety standard before you ever leave the pit lane. The K&N KN-204-1 Racing Oil Filter is built to satisfy those requirements without compromise — featuring a safety-wire drilling as standard, a double-rolled seam base plate, and a high-flow synthetic filter medium engineered to protect your engine at race RPM and beyond.
Key Features
- Safety-wire drilling as standard — satisfies mandatory scrutineering requirements at circuit events without modification.
- 17 mm hex nut for tool-free removal with any common spanner, eliminating fumbling in the pits between sessions.
- Anti-drainback valve prevents dry starts by retaining oil in the filter when the engine is off — critical protection during cold starts and after prolonged storage.
- Updated pressure relief valve optimises oil flow and guards against overpressure conditions, even under sustained high-rev race use.
- Walls 50% thicker than standard filters, reinforced base plate with double-rolled seal — built to withstand the mechanical and thermal stresses of track conditions.
- Modern synthetic filter medium traps dirt, metal particles and contaminants while maintaining a high flow rate compatible with fully synthetic and race-spec engine oils.
- Pre-lubricated O-ring ensures a clean, leak-free installation every time — no additional sealant required.
Built for the Circuit, Ready for the Road
The KN-204-1 is not simply a rebadged road filter. Every design choice — from the safety-wire boss to the reinforced canister walls — addresses the specific demands of track riding. At high RPM, oil pressure spikes and temperature extremes that would stress a standard filter are handled with authority by the K&N's heavy-duty construction. The synthetic filter medium continues to deliver excellent filtration even when oil temperatures climb well above the thresholds seen in everyday street riding.
For R3 owners who use their machine on both road and track, the KN-204-1 fits seamlessly into a standard oil-change routine. The pre-lubricated O-ring, combined with the 17 mm hex, means installation and removal take minutes rather than a frustrating battle with proprietary tooling. K&N's more than 50 years of filtration engineering underpin every unit — consistency and reliability you can count on service after service.
