BUILT BY RACERS, FOR RACERS

In the early 1960s, two innovative motorcyclists—Ken Johnson and Norm McDonald—developed an unconventional new air filter design, engineered to perform under the demands of the dusty, silty racing tracks of the California desert. Five decades later, K&N continues to be an industry leader and pioneer in technology, offering thousands of exceptionally-engineered performance products to automotive enthusiasts worldwide.

There’s a reason top racers trust K&N to protect their trophy trucks in the Baja 1000, premium racecars in 24 Hours of Le Mans, and 10,000-horsepower Top Fuel dragsters—K&N filters keep dirt out, and let airflow in.
