Has anyone put a Airaid "poweraid" throttle body spacer on thier 4.7? If so does it live up to the advertisement? If I even get one more mpg and one or two more horses for $100 its a good deal...
welcome dude.. please search about the common mods (intakes, exhausts, TB spacer, etc). btw TB spacers do nothing for fuel injected engines, at least nothing noticeable power and mpg wise.
