So far, I have driven my with K&N filters and I haven't notice any increase in the mileage but I do feel that the auto is breathing much easier... I have always replaced the stock filters with the K&N filters for years... I am consistently checking my dashboard to see if the AMS lights up... Hope the warning light doesn't light up !!!
