Description K&N 57-0615 Performance Air Intake System MAZDA 6 L4-2.3L F/I, 2002-2006

K&N 57i Series induction kits are engineered for each specific vehicle to eliminate the size limitations of the factory air box. These kits are designed in various forms depending on vehicle characteristics and available engine bay space.

Each kit delivers power gains across the RPM range. The open-air filter design offers increased surface area for greater airflow and reduced restriction compared to K&N O/E replacement filters. The larger filter also captures more dirt, extending service intervals up to 100,000 miles before cleaning is needed.

The filter may be attached directly to the carburetor or throttle body, or indirectly via a tube assembly. All adapters are constructed from high quality materials such as steel, aluminum, silicon, or reinforced nylon for durability. 57i Series Intakes are not legal for use in California or other states adopting California emission standards.
