IWG75 Porsche 996 (911) GT2 Black 24PSI



The Porsche 996 GT2 Internal Wastegate Actuator (IWG) provides better turbo response and greater sensitivity when managing boost pressures. Designed as a direct bolt-on replacement for the factory part, the Porsche IWG is easy to install and requires no special tools or fabrication. We've taken the proven technology from our WG38, 40 and 45mm External Wastegates and applied it to the Internal Wastegate Actuator.
