K & N air filters are designed to achieve high, virtually unrestricted air flow whilst maintaining filtration levels critical to ensure long engine life, as well as generally adding 1-4 horsepower to your bike.
K & N's high flow cotton gauze air filters are washable, reusable and built to last for the life of a motorcycle engine. Filters consist of four to six sheets of cotton gauze layered between two sheets of aluminium 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 your engine, is washable and reusable, and will protect your engine for the life of your vehicle.
