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.
