The Turbosmart IWG75 Twin Port is an upgraded internal wastegate actuator for BorgWarner EFR B1 twin-scroll turbochargers. It replaces the factory actuator with a stronger billet unit that has a higher working ratio for sharper boost response, and its twin-port housing widens the boost-control window. It uses a 140mm rod and is preset to 14 PSI. Black.
