Love Your Car, Love the Environment

Over 100 million disposable air filters end up in landfills each year. Choosing a washable, reusable product that lasts for the life of your vehicle helps to reduce unnecessary waste.

Protect critical systems

When using a poorly-designed disposable air filter, dust, dirt, and contaminants can make their way into your engine—causing damage and premature wear. In addition, an inefficient oil filter can allow oil contaminants to build up within the engine, reducing its working lifespan. K&N performance protection products are designed to keep contaminants where they belong—out of your engine.

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.
