Over the past 2 years I have added aftermarket accessories to my 2012 F-150 to improve mileage. The Taylor Cable Helix Power Tower Throttle body spacer looks good an easy install and did increase mileage. The throttle body spacer, Airaid Intake, AFE 4" exhaust,and Tonnopro trifold bed cover have increased my mileage from 18.5 mpg to 21.8 a 3 mpg gain average. As with any add on your MPG is going to depend on how you drive, overall with cruise control at 70 mph on the interstate 21.8 is fair.
