does anyone know anything about these vortex generators that are suppose to increase gas mileage and horsepower...kinda sounds like bs to me but i thought id ask you guys?
The tv show Mythbusters put it to the test, and they determined it to be BS. But I've seen people on this board and other boards say it works. Maybe it's a psychological thing?
I think they are all BS. If the OEM's could squeeze more MPG with a simple tweek like that they would do so to meet government regulations and sell more vehicles.
