Turbosmart IWG75 2015 Subaru Impreza WRX 7 PSI Black Internal Wastegate Actuator

The Turbosmart IWG75 Internal Wastegate Actuator is built with a proprietary silicon Nomex diaphragm and stainless steel rods, offering more precise control over exhaust gas flow to your turbocharger than the stock unit. This well-built actuator is designed to give your factory-frame turbocharger better boost response across the entire RPM range. It features a high-grade billet aluminum construction for durability and a unique locking collar system for secure adjustment.

Compared to the factory actuator, the IWG75 series has an improved 'Working Ratio.' This means it can manage boost pressure more effectively, helping to prevent overboosting and ensuring consistent power delivery. The included 7 PSI spring is a popular choice for drivers looking for a noticeable improvement in how quickly the turbo spools up without being overly aggressive.

This actuator is a direct fit for your 2015-2021 Subaru WRX. While it offers improved performance, please note that it is not CARB approved and cannot be shipped to California.
