 I am a firm believer in K@N products and the lifetime guarantee. K&N air filter is the first thing I buy for any car truck or atv that I own. I put a K&N air filter on my 1985 Suzuki LT250R 5 years ago, after all the racing and trail riding the filter has taken a beating. Called K&N service dept. and spoke with Emily about my old filter, they are sending me a brand new filter for free. Thank you Emily and K&N for the awesome service you provided me. I recommend K&N products to anyone!
