I already have a cold air intake and an edge chip so Im getting ok gas milage but I drive a lot and am looking into all the possibilities. What do you guys think or know about throttle body spacers? Besides the fact that they sound cool. Also I was just looking online and came across these metal fan like things that you put in your intake tube that supposably increases the air flow and gives you better gas milage??? Does anybody know anything at all about these? Thanks!!

 

The metal thing in the intake is junk. Look here for more fuel mileage reccomendations. https://www.f150forum.com/search.php
