MILEAGE IMPROVER - Electric Line's Gas Saver Air Foil Stabilizer holds your pickup's tailgate at a 45-degree angle to reduce wind resistance and improve gas mileage. The kit includes two cables for each side of the tailgate: one allows it to open fully, the other holds it partway open. In testing on a Ford F-250 diesel 4x4, top speed increased by 15 mph and each tank of diesel lasted from 20 to 54 miles longer.
