• Upgrade Your Ride: Turbosmart's IWG75 Wastegate Actuator offers maximum boost response for your factory frame turbocharger! • Enhanced Performance: With an increased 'Working Ratio', enjoy improved boost response across the RPM range. • Superior Design: Featuring a proprietary Silicon Nomex Diaphragm, high - grade billet aluminum construction, and Turbosmart's unique locking collar system. Turbosmart Upgraded Wastegate Actuators are engineered to provide the best possible boost response for your factory frame turbocharger. The IWG75 Series has an improved 'working ratio' over factory equipment, thanks to an increased diaphragm surface area and spring revisions. This results in better leverage against boost and backpressure while remaining super - responsive. Upgrading with the same base pressure as the factory gives you a broader boost and torque curve, with peak boost achieved earlier and held longer. Higher base pressures can amplify these improvements, but tuning and recalibration may be needed. You can choose springs from 3psi to 26psi (optional). The 14 psi version directly replaces the factory item, while other versions require ECU tuning/calibration.

Use this Turbosmart IWG75 Wastegate Actuator when you want to enhance the performance of your Mitsubishi EVO 9. It's perfect for car enthusiasts and those who love to tune their vehicles. This actuator is made of high - grade billet aluminum and comes with stainless steel rods and clevis. You can select springs with pressures ranging from 3psi to 26psi to suit your needs. Just note that the 14 psi version can directly replace the factory part, while others need ECU tuning.
