The Turbosmart wastegate actuator range has been designed as a stronger, more reliable replacement for OEM parts. Like all Turbosmart parts, billet construction means they are stronger and more durable than a stock actuator, while Turbosmart’s focus on performance means boost comes on faster and holds on longer, putting you in control!
Subaru WRX STi 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 Subaru WRX STi 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.
Comes pre-configured with a 7psi spring pressure.
