"not too hard to install, instructions could be a LITTLE more detailed but no serious issues. noticed a slight increase in power and mpg but ive only ran 2-3 tanks. sounds nice under the hood when revved above 2500 rpm but at around 2000 rpm there is a very high pitch whistle...and no its NOT a leak, everything is tight as it can go. i'm thinking it's either the throttle body or some other part but i'm not sure. anyway, good little boost for a not-too-expensive add-on." —Andrew D from Newberg, OR bought a K&N 77 Series Metal Intake Kit for a 2001 Ford Explorer, Sport Trac, 4.0L V6, manufactured after 7/24/2000.
