DescriptionThe whole story▼

Engineered from the ground up for sealed tarmac circuits, the K&N SU-7506R Racing Air Filter is built to a specification that goes well beyond the standard K&N road offering. The multi-layer oiled cotton gauze medium is housed in a precision-formed frame, maximising airflow while maintaining the filtration integrity that race engines demand. If you are chasing every last horsepower from your GSX-R on track, this is the filter that belongs in the airbox.

Key Features

  • Race-grade multi-layer oiled cotton gauze construction delivers a measurably higher airflow rate than the OEM paper element, translating directly into sharper throttle response and stronger top-end pull.
  • Purpose-built for closed tarmac circuit use — the filter medium and frame are optimised for the consistent, controlled conditions of a race environment rather than the varied demands of road or off-road riding.
  • Excellent particle filtration protects combustion chambers and valve seats from fine dust and debris without restricting the airflow the engine needs at race rpm.
  • Direct OEM-replacement fitment means no modification to the airbox — drop the filter in and go, with no additional hardware required.
  • Not homologated for road use — intended exclusively for track and competition applications.

Build Quality and Materials

K&N's racing filters are constructed to tighter tolerances than their washable road equivalents. The pleated cotton gauze is layered and precisely oiled at the factory to achieve a balance between maximum airflow and dependable filtration under sustained high-rpm conditions. The supporting wire mesh and formed rubber sealing bead ensure the filter seats cleanly in the airbox, eliminating bypass air that could allow unfiltered charge into the engine. It is this attention to material selection and assembly quality that has made K&N the default choice in professional pit lanes for decades.

Track Performance

On a highly tuned GSX-R 600 or 750, even small restrictions in the intake tract carry a measurable cost in peak power. The SU-7506R removes the stock paper filter as a performance bottleneck, allowing the engine management system and fuel injectors to work with the volume of air the engine is capable of consuming. Riders running aftermarket exhaust systems or ECU remaps will see the most pronounced gains, as the intake side of the equation finally matches the improved exhaust flow.

Fitment and Compatibility

The K&N SU-7506R is a direct-fit racing air filter for the following models:

  • Suzuki GSX-R 600 — model years 2006, 2007, 2008, 2009, 2010
  • Suzuki GSX-R 750 — model years 2006, 2007, 2008, 2009, 2010

No airbox modifications are required. Always verify your specific model year and variant before fitting.
