The Helix Power Tower Plus™ throttle body spacer increases fuel economy while significantly increasing horsepower and torque by producing air breakup and turbulence that yields greater fuel burn efficiency, which translates into the best performing and most efficient throttle body spacer in the marketplace! Which in turn translates into more savings at the gas pump for you. The AirMax™ Spiral Flow Cold Air Intake System increases air volume and causes a vortex which creates a turbulent air spiral! This increased air volume and vortex-like air action creates a turbulent air flow, that when combined with fuel is more efficiently burned in the combustion chamber. The improved fuel burn results in newfound power, better torque and improved fuel economy from your stock engine. No other fresh air induction system can match the quality and engineering of the AirMax™ Spiral Flow Cold Air Intake System. Of course the best possible scenario would be to have both the Helix Power Tower Plus™ Throttle Body Spacer and the AirMax™ Spiral Flow Cold Air Intake from Street and Performance Electronics installed... Since both products are manufactured by the same company there is absolutely no worry as to whether they will be compatible. They were designed to complement each other, yielding exponential gains when used in tandem, saving you literally hundreds if not thousands of dollars a year at the pump.
