This system is intended to be an easy direct fit installation for all 2015 and up C7 Z06 model Corvettes. This Unique Design adds 1.75 Gallons to the vehicle’s heat exchanger cooling system. The Granatelli hand built 6061-T6 expansion tank is a simple installation using all factory hardware. With slight modification to one hose, the installation on a cool engine should take no more than 30 minutes. Additionally, the intercooler expansion tank has a built in spray bar, ensuring even flow of coolant and/or water across the entire tank. A built in petcock valve allows for easy emptying of the tank, to replace the coolant after an event. The Granatelli unique design mimics the same taper and angle of the OE engine cover giving it a true stylized look while increasing capacity. A must for anyone increasing boost levels to the engine or just doing spirited extended driving. Total OEM looking finish and installation appearance.
