K&N's replacement air filters are designed to increase power and acceleration while providing excellent filtration. Washable and reusable, these filters are specially designed to fit into the existing air filter housing.
Increasing performance is easy, on most vehicles you simply remove the original disposable air filter and replace it with a K&N.
The standard K&N replacement air filters for motorcycles (normal street use) are covered by the famous K&N Million-Mile Limited Warranty™ and will be the last air filter you ever replace on your vehicle!
