Turbosmart IWG75 Wastegate Actuator - Seat Leon Cupra R (1M) K04 - 5psi
The Turbosmart IWG75 is an upgraded internal wastegate actuator for the factory K04 turbocharger fitted to the 1.8 litre turbo engine in Seat, Volkswagen and Audi models, including the Seat Leon. 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 K04 turbo only - 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
