Turbosmart IWG75 7 PSI Black Internal Wastegate Actuator for 2004-2020 Subaru WRX/STi
Turbosmart Upgraded Wastegate Actuators are designed to enhance your factory frame turbocharger's boost response, offering superior performance across the entire RPM range. The Turbosmart IWG75 Series features an increased ‘Working Ratio’ over stock equipment, which results in quicker and more precise boost response. This is achieved by expanding the diaphragm’s effective surface area and optimizing the spring design, providing more leverage against boost and backpressure forces.
With the same base pressure as the factory unit, these actuators deliver a wider boost and torque curve, helping you reach peak boost earlier and maintain it at higher RPMs. For those seeking even more performance, increasing the base pressure can further improve response, though tuning and recalibration may be necessary to maximize benefits.
