BUILT TO PROTECT


K&N air filters collect and trap particulate matter in a manner very different from disposable filters. A paper filter exhibits a principle called “surface loading”—dust collects only on the surface of the media. In contrast, K&N filters utilize “depth loading”, in which multiple layers of cotton fibers provide particle retention on multiple levels, and the media also features pleats to increase surface area over disposable filters. As a result, K&N filters are able to hold significantly more dirt and particulate matter per square inch of media over an average paper filter.

EXTENSIVELY TESTED


K&N performance air filters go through a rigorous testing process—simulating challenging real-world conditions—to ensure that they provide exceptional engine protection. Each filter is designed to provide a high level of airflow while simultaneously targeting an overall filtration efficiency of 98%. Your High-Flow Air Filter? is protected by K&N’s 10-Year/Million Mile Limited Warranty.

ENGINEERED TO LAST


One High-Flow Air Filter? is designed to last for the entire lifespan of your vehicle. Under laboratory conditions, a K&N air filter was washed and re-oiled more than 100 times and still provided an exceptionally high level of engine protection and airflow. K&N High-Flow Air Filters? require servicing once every 50,000 miles under normal highway driving conditions—and the oversized, conical High-Flow Air Filters? included with some air intake systems only need servicing every 100,000 miles under normal highway driving conditions. K&N high-flow oil filters, cabin filters, fuel filters, and intake systems are all designed to have long service lives while maintaining outstanding performance.

OUR STORY

WHY K&N?


K&N is the home of the original red oiled air filter. In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a ground-breaking new idea for an oiled air filter. 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. Thank you for helping us reach 50 years in business!
