I noticed a slight improvement in throttle response. None of the 'annoying whistle' that others have mentioned...just a minor slight hum during acceleration. Feul economy improved by approx. 2.5-3 mpg's, but that improvement decreased after installing a K&N FIPK intake kit. I would purchas this product again for this vehicle or any other...it was worht the small investment.
