*Granatelli 0 ohm wires are patent protected by United States Patent number 7,185,622. This patent covers their unique method of producing ignition wires of extremely low resistance while maintaining very high noise suppression. The benefit of this invention is that full electrical energy from the ignition source is transmitted to the spark plug. The end result of the application of this method is increased horsepower, torque and fuel economy.
