"i got 1 MPG more on my first trip of 400 miles with the use of the this product !!! which is awesome for the price tag of $ 100 thanks !!!" —Alan B from Oaklyn, NJ bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2003 Ford Expedition, 5.4L V8.
"We live at 8500 ft. in Colorado, so any improvement in power/torque/mpg in the thin air is great. Installation was 30-40 minutes with simple hand-tools in the driveway. Our Expedition w/5.4 liter Triton V8 pulls better on grades, does not need to "drop-down" to lower gears so often, and mpg's are up between 1.5-2.0 miles per gallon. Acceleration is better too, I recommend this to any Ford Expedition owner." —Mark S from Evergreen, CO bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2003 Ford Expedition, 5.4L V8.
