I have a barely used Dual Pass High Capacity Shelby GT500 Heat Exchanger for a 2007-2009 gt500. This heat exchanger dwarf's the factory Shelby GT500 unit and provides an over 200% cooling capacity increase in Shelby GT500 applications. This results in substantially reduced air inlet temperatures increasing supercharger power output under all conditions. $300 includes shipping. 315-254-6602 Tim
