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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Suits the K03 turbo only - not the K04 fitted to higher-output versions such as the S3. Turbosmart also lists the 1.8T K03 Skoda Octavia and Seat Leon. 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\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?
