First of all, it fits better than the original Motorcraft (or whatever brand) filter was in there.
The boost in performance is noticeable. My old filter wasn't really dirty; I just knew I wanted to engine to breathe better, and man does it. Much more effortless torque and acceleration, and the idle is so smooth and quiet now.
I would put this filter on a par with changing the oil in your engine and your transmission to really nice synthetic oils, maybe better. My Explorer runs like new.
