IWG75 Wastegate Actuator Suit Subaru WRX 1997-2007 TD04 (7PSI)

Turbosmart Upgraded Wastegate Actuators have been developed to provide the maximum possible boost response for your factory frame turbocharger. The Turbosmart IWG75 Series of upgraded Actuators benefit from an increased ‘Working Ratio’ over the factory equipment, resulting in improved boost response throughout the RPM range.

This improved ‘working ratio’ is achieved through an increase in the effective surface area of the diaphragm and revisions to the actual springs fitted, resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.
