K&N Filters

K&N Filters has been at the forefront of the automotive filtration industry for more than 50 years, offering top-of-the-line products that increase performance, protection, and longevity across thousands of vehicle applications worldwide.

The company's roots can be traced back to the early 1960s when two motorcycle racers, Ken Johnson and Norm McDonald, came up with a revolutionary idea for an air filter that could withstand the demands of dusty and dirty off-road environments. After extensive experimentation, they discovered that an oiled cotton design provided optimal efficiency and could be washed and reused. Thus, the original K&N® High-Flow Air Filter™ was born.

Today, K&N® continues to lead the industry in filtration technology, providing outstanding protection for everything from top-fuel dragsters to everyday commuter vehicles. In addition to performance air filters, K&N® manufactures a range of other protection and performance products, including air intake systems, oil filters, fuel filters, cabin air filters, and home air filters.

K&N® products are designed and manufactured in-house, with a headquarters in Riverside, California, spanning nearly 400,000 square feet. The company also operates facilities in Grand Prairie, TX, England, China, and the Netherlands, with departments dedicated to engineering, product design, manufacturing, warehousing, testing, purchasing, sales, customer service, marketing, and corporate offices. With a reputation for exceptional quality and customer service, K&N® continues to set the standard in the filtration industry.
