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. It is a bolt-on fit with a vehicle-specific bracket.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Suits the factory K04 turbocharger 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.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIWG75 wastegate actuator\u003c\/li\u003e\n\u003cli\u003eVehicle-specific mounting bracket\u003c\/li\u003e\n\u003cli\u003eSpring pre-fitted to the listed pressure\u003c\/li\u003e\n\u003cli\u003eFasteners and swivel hose barb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNeed help confirming fitment?
