The Econo Maxx, an air accelerator constructed of high-grade automotive polyurethane, combines the Vortex and Venturi scientific principles to achieve a cooler, quicker, denser charge of air. The non-moving fins spiral as the diameter decreases and the resulting whirling effect produces a better air-fuel mixture, improves air flow, decreases emissions and increases horsepower and torque, according to the company. For best results, two to three tanks of fuel should be consumed, which will aid in the removal of carbon deposits and allows for higher engine performance.
