K&N Engineering

K & N Engineering, Inc., "manufacturer of the world's best air filters", has been the innovative leader in air filter technology since 1963, serving the needs of the automotive, motorcycle, marine , industrial and military markets. Located in Riverside California, K & N also has another manufacturing facility in the United Kingdom.

K & N first developed air filters specifically for the motorcycle racing market. With the success K & N experienced in the motorcycle market, the Company decided to branch out to the automotive Motorsports market. K & N quickly grew to be the world's most widely used performance air filter in both the automotive and motorcycle markets.

Today, K & N equips about 80% of all off-road racing vehicles and wins in every major off-road event in the world, including Pikes Peak, the Baja 500 & 1000 and the grueling Paris to Dakar race. K & N also dominates the world's most prestigious and technical racing association with nine of twelve Formula One Teams using K & N air filters.

To keep on the cutting edge of technology, K & N has its own technical facilities that are devoted to product development and testing. The facilities have in-the-floor-chassis dynamometers, to ensure that all K & N air filters are technically designed for the highest increase in horsepower. Air restriction testing and development has yielded products such as our Generation II Fuel Injection Performance Kits, which lead the industry in horsepower gains!

K & N has capitalized on their superior racing heritage along with its superior air flow, increased dirt filtration, environmental friendliness and exclusive ten year, million mile limited warranty to catapult itself to the front of the performance air filtration industry. K & N has garnered numerous awards from SEMA, including "Manufacturer of the Year, 1994, 1996, 1997, and 2000".
