My longtime boyfriend was a motorcycle mechanic for many years who introduced me to K&N products and I have used them for years. Every vehicle I own has a K&N air filter and now my 4 wheeler will have a K&N oil filter. Your website is very convenient to use and I received the correct part very quickly. Thanks.
