OUR STORY
WHY K&N?
K&N is the home of the original red oiled air filter. In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a ground-breaking new idea for an oiled air filter. Five decades later, K&N® is still innovating industry-leading filtration technology, and offers outstanding protection for everything from top-fuel dragsters to commuter vehicles across the globe. Thank you for helping us reach 50 years in business!
