Fuel Saver is a non-moving, turbine shaped device which creates a vortex or swirling effect to the incoming air. The Fuel Saver installs easily in your air inlet hose and its unique airflow dynamics create a swirling, 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 EPA-licensed emissions lab.
