DescriptionThe whole story▼
Engineered for those who demand more from every service interval, the K&N KN-204-1 racing oil filter is built to keep your Honda CBR 1000 RR running at its absolute best whether you are chasing lap times on track or clocking hard miles on road. A purpose-designed drop-in replacement for SC57, SC59 and SC77 chassis spanning 2003 to 2019, it combines high-flow filtration with a construction robust enough to handle sustained high-rpm punishment without compromise.
Key Features
- 17 mm hex nut integrated into the canister body for removal with standard workshop spanners — no strap wrench or special tools required.
- Safety-wire drilling provision allows the filter to be lock-wired in place to meet race and trackday scrutineering requirements.
- Pre-greased O-ring cartridge seals ensure a fast, clean installation with zero mess and a reliable leak-free fit from the first start.
- Anti-drain-back valve retains oil in the filter after shutdown, eliminating dry starts and protecting bearings at the critical moment of ignition.
- Updated pressure-relief valve optimises oil flow under extreme load conditions and guards the engine against pressure spikes.
- 50% thicker canister wall and a reinforced base plate with double-rolled seam deliver substantially greater structural strength than standard OE filters.
- Advanced synthetic filter media provides outstanding contaminant capture while maintaining a high flow rate, and is fully compatible with synthetic engine oils and race fuels.
Built for the Track, Proven on the Road
The KN-204-1 was conceived with racing applications firmly in mind. The safety-wire port and heavy-duty canister construction address the demands of circuit use directly, while the anti-drain-back valve and double-rolled base plate seal mean road riders benefit equally from dependable cold-start protection and a leak-proof seal across extended service cycles. The synthetic filter medium maintains filtration efficiency even when oil temperatures climb well beyond normal operating ranges, making it as capable at a trackday as it is during a long touring run.
Filtration Without Restriction
One of the key compromises in OE oil filtration is the trade-off between flow rate and filtration quality. K&N addresses this with a modern synthetic media formulation that captures dirt and particulate matter with high efficiency without restricting the volume of oil reaching critical engine components. The result is cleaner oil circulating more freely — a measurable benefit for both engine longevity and sustained power output under hard use.
Fitment & Compatibility
The K&N KN-204-1 oil filter is a direct, no-modification replacement for the following Honda models:
- Honda CBR 1000 RR SC57 (2003–2005)
- Honda CBR 1000 RR SC59 (2008–2011)
- Honda CBR 1000 RR SC77 (2012–2019)
Always verify your chassis code and model year before fitting. Installation should follow Honda's recommended torque specifications for the oil filter thread.
