K&N spray oil for K&N sports air filters

For over 50 years, K&N has been an industry-leader in automotive filtration technology offering products to increase performance, protection, and longevity in thousands of vehicle applications for consumers worldwide.

In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a groundbreaking new idea for an air filter that could work in dusty and dirty terrain. After experimenting with many types of filter media, they found that the combination of oiled cotton not only allowed the filter to trap dirt very effectively, but also allowed it to be washed and reused, and thus the original K&N air filter was born. Five decades later, K&N is still innovating cutting-edge filtration technology, offering superior protection for everything from the most fuel-efficient dragsters to everyday vehicles around the world.
