2003 Ford Explorer 4.0L V6 - All Models
Performs as advertised (which is something that happens less and less these days). Added fuel economy (especially if you clean your MAF during install), better sound from the engine, and I can feel a slight improvement in throttle response and horsepower (although I didn't get it for that). All in all, a quality purchase that did what was intended and improved performance.
