For over 50 years, K&N? has been an industry-leader in automotive filtration and 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 ground-breaking new idea for an air filter—one that could perform under the demands of dusty, dirty off-road environments. After experimenting with numerous types of filter media, they discovered that an oiled cotton design allowed the filter to not only capture contaminants very efficiently, but also allowed it to be washed and reused, and the original K&N? High-Flow Air Filter? was born. 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.
In addition to performance air filters, K&N? now manufactures a variety of other protection and performance products, including air intake systems, oil filters, fuel filters, cabin air filters, and home air filters, with a reputation for exceptional quality and customer service that millions of customers trust.
K&N? has maintained active involvement in racing and motorsports throughout its history, and has sponsored championship-winning teams in most subdisciplines of motorsport. A long and storied racing heritage continues to contribute to the development of products for all types of vehicles and engines.
K&N? is headquartered in Riverside, California, in a ten-building complex spanning nearly 400,000 square feet, and also operates facilities in England, China, and the Netherlands. K&N facilities include departments for engineering, product design, manufacturing, warehousing, test facilities, purchasing, sales, customer service, marketing, and corporate offices. Most K&N products are designed and manufactured on-site.
K&N? continues to commit to the high level of quality, customer service, and innovation that has earned the trust and loyalty of drivers for over half a century.
