I read they boost a car's fuel efficiency (by changing the fuel/air mix). If this is true than why hasn't GM or Ford bought the company that owns the patent?

my hubby put one on the car....it didnt do anything for the fuel efficiency. I did sorta feel like it was a lil zippier. Who knows. I dont think it works though...cuz he took it off and I never even noticed it until tonight. ...( I just asked him about it and he said he took it off a month ago..lol)

I just saw a test done on those by a local consumer reporter, and the conclusion was the vortex does nothing to improve fuel economy or power. I can't say I was terribly surprised, as the design would be very inexpensive for manufacturers to incorporate into the air intake, and being constantly pressured by the C.A.F.E. standards to improve fleet economy they would likely make use of the concept if it were not an expensive add-on.
Your easiest and cheapest fixes to fuel economy are to be had by keeping the car in tune, the air filter clean, and the tire pressures relatively high, but still in the recommended range for your vehicle. Tire pressure alone can affect mileage fairly significantly, as firmer tires reduce rolling friction.

If these are magnet thingies you attach to part of your engine, I've heard that they don't do a darned thing. Usually they come with instructions to adjust your carburator, which improves short term efficiency but at a cost of long term endurance.
