In the early 1960s two motorcycle racers Ken Johnson and Norm McDonald (K&N) developed a ground-breaking new idea for an air filter. 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. 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 with a reputation for exceptional quality and customer service.

The K&N replacement air filter for RK Series air cleaner assemblies is designed to increase horsepower and acceleration while providing excellent filtration. The air filter is washable and reusable and designed to be used as a replacement air filter for specific K&N RK Series air cleaner assemblies for Harley-Davidson® motorcycles.
