The Subaru WRX has long been an icon of the turbocharged performance car world. The latest WRX continues the tradition with its powerful and charismatic 2.0-litre turbo Boxer engine and trademark all-wheel-drive.
Turbosmart is committed to offering the best products to enhance the performance of this sports sedan. The IWG-75 Internal Wastegate Actuator is the latest addition to Turbosmart's range of products designed specifically for the 2015 WRX and WRX STi.
Turbosmart's IWG-75 Internal Wastegate Actuator allows more precise control over the flow of exhaust gas to the turbocharger compared to the stock actuator, creating a flatter, more stable boost curve with less drop off at the end of the rev range. The result is a more drivable car with better turbo response, smoother power delivery and less lag.
Turbosmart's Internal Wastegate Actuator can cope with the high stresses and temperatures of high boost applications for prolonged periods of time, and is highly customizable with interchangeable springs for a range of boost levels. Stock actuators can struggle to cope with the pressures of increased boost, so the IWG-75 is a must for the WRX enthusiast looking for more power while avoiding damaging boost spikes.
Features: - Silicone diaphragm with Nomex reinforcement to withstand high temperatures
- High grade, billet aluminum construction
- Stainless steel rods and connecting clevis for corrosion resistance
- Locking Collar design cap allows for quick spring changes
- Ideal for use with any Turbosmart boost controller

Providing better turbo response and greater sensitivity when managing boost pressures, Turbosmart Vehicle Specific Wastegate Actuators provide better turbo response and greater sensitivity when managing boost pressures. Designed as a direct bolt-on replacement for the factory part, the actuator is easy to install and requires no special tools or fabrication. It can't get any easier!
What is an internal wastegate actuator? On an internally wastegated turbo, the wastegate valve is built into the turbine housing. The wastegate valve is controlled by an internal wastegate actuator. As boost rises the actuator controls the position of the wastegate valve, which in turn controls the exhaust gas flow to the turbine.
