I hear all the time about that tornado that is suppose to make a vortex of air that increases mileage and power. I myself think its BS but others tell me it works, read many forms on sites saying they lost power and mileage. My uncle has a 97 grand marquie and he swears by the tornado. I know every car is different but is it BS or what?
