K&N Air Filters increase performance and horsepower. K&N is the innovator of a unique cotton air filtration system. K&N Air Filters are washable and reuseable. K&N Air Filters will enhance the performance and protect your engine. K&N 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 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.
