The Tornado fuel saver
The Tornado’s unique airflow dynamics creates a swirling vortex of air causing a fast-burn effect in the combustion chamber. This creates finer particles (atomized fuel), allowing better flame propagation and more complete combustion, resulting in gas mileage increases averaging 1 to 2 MPG. These figures are confirmed by road testing performed at an emission lab licensed by the EPA
The swirling effect or Vortex effect, is exactly what GM had in mind when making there Vortec engines that swirling effect has proven to make horsepower and increase your fuel mileage.
