K&N Engineering

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.

Cold Air Intakes

K&N cold air intakes are guaranteed to increase horsepower and torque, and are custom-designed for specific makes, models, and years to help ensure a precise fit and easy install. K&N air intakes install in less than an hour and come with detailed, step-by-step instructions that are included to help ensure your installation goes smoothly and is done correctly the first time. 

Many intakes are now offered with both a dry synthetic and oiled cotton filter options.  If your kit includes an oiled filter, it only requires cleaning every 100,000 miles under normal highway driving conditions (as opposed to 15,000-20,000 miles for a disposable filter), and a K&N Dryflow filter can go up to 50,000 miles before cleaning.  Experience the convenience of a K&N Dryflow intake kit with a no-hassle, oil-free air filter for easy maintenance. Or go with the intake sold to millions of consumers with a high-flow oiled cotton air filter.  Both are proudly made in the USA for trusted quality & reliability.

K&N performs rigorous in-house testing to ensure that each air intake system meets high-performance standards. Whether you need a K&N performance air intake system for your car or truck, RV, heavy-duty truck, or performance sports cars, you can trust K&N to have the air intake kit that best fits your specific needs.
