Cotton breathes better than paper. Ken Johnson and Norm Macdonald, two gearheads from California knew this and applied it to their motorcycles. The result was a washable, reusable filter that performed fantastic for their race bikes. Ken and Norm eventually patented their innovated air filter and transformed their small motorcycle accessory business in to the most successful air filter company in the world. For nearly fifty years, the name K&N has been synonymous with high performance air filters.
A quality air filter does more than dress up your engine; it keeps harmful dirt and grime from destroying it.
