Turbosmart IWG75 Wastegate Actuator - Volkswagen Golf GTI (Mk6) K03 - 5psi
The Turbosmart IWG75 is an upgraded internal wastegate actuator for the K03 / IHI turbocharger variant fitted to Volkswagen Audi Group engines, including the Volkswagen Golf GTI (Mk6). A larger effective diaphragm area and revised springs give it a higher working ratio than the factory actuator, so peak boost arrives earlier in the rev range and is held for longer, giving a broader boost and torque curve.
Note: Suits the K03 / IHI turbo variant - please confirm your turbo before ordering. Running a higher base spring pressure than factory is likely to require ECU tuning and recalibration. Installation by a professional is recommended.
What's Included
- IWG75 wastegate actuator
- Spring pre-fitted to the listed pressure
- Fasteners and swivel hose barb
