For over 35 years K&N has manufactured serious air filters completely unlike traditional disposable filters. K&N
air filters are designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical
to ensure long engine life. The secret to K&N's success lies in the unique characteristics of their filter medium that
was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. They just
wanted to win races and stumbled on a cotton filtration technology destined to be great. K&N's high flow cotton gauze
air filter is washable, reusable and built to last for the life of your engine. The filters consist of four
to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled
to enhance its filtering capabilities and overall performance. The result is an air filter that allows dramatically
more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle.
K&N Replacement Air Filters are ideal for extended use in dirty and dusty off-road riding and provide clean carburetion even at high altitude. As a rule, no jet changes are required with just a K&N air filter element, however the spark plug condition should be checked for proper mixture after the first few miles of riding. If the airbox has been modified for increased air flow, the main jet size will need to be increased to provide the proper fuel mixture.
