I have used K&N filters in seven cars over the last seven years. Three Chrysler Concordes,a Ford Aerostar,a Ford Windstar, a Jaguar XJ8, and a Chevy Impala LTZ. I have found the filters to be more economical as the miles pile up. Performance enhancement is subjective as I don't have the means to test it, but it seems to be there.
