Located in Riverside California, K & N also has another manufacturing facility in the United Kingdom.
K & N first developed air filters specifically for the motorcycle racing market.

To keep on the cutting edge of technology, K & N has its own technical facilities that are devoted to product development and testing.

Air restriction testing and development has yielded products such as our Generation II Fuel Injection Performance Kits, which lead the industry in horsepower gains!
