• Ultimate Engine Protection: Features multiple layers of oiled cotton gauze media, providing up to 99% filtration efficiency against road grime and track debris.

• Washable & Reusable: A permanent upgrade; simply clean and re-oil to restore to peak performance. This is the last air filter you'll ever need to buy for your CBR.

Why Choose K&N for your 2004-2007 Fireblade?

The 2004–2007 CBR1000RR (SC57) was the first generation to feature the gravity-fed Ram-Air system and Dual Stage Fuel Injection (DSFI). The HA-1004 is specifically engineered to work with this pressurized intake system. Unlike standard paper filters that can "choke" under high-velocity air, K&N’s high-flow cotton media thrives under pressure, ensuring your Fireblade maintains its iconic scream and relentless power delivery all the way to the redline.
