TurboSystems HTX4268B1 Turbocharger

Responsible for controlling the amount of boost pressure the Focus's turbo can generate, the wastegate plays a fundamental role in the turbo system. However, the standard Focus actuator does not allow the Focus to reach its full potential, even at standard boost pressures. OEM wastegate actuators typically use soft springs, which begin to open long before peak pressure is reached. The result is that you don't get all the boost pressure you could. Turbosmart's IWG-75 internal wastegate actuator is a 14 PSI rated actuator designed with performance and reliability as key priorities. The Turbosmart actuator provides faster boost pressure build-up and less drop at high RPMs, with a more responsive and stable boost pressure curve. The results of installing a Turbosmart IWG on your Focus RS are truly impressive, providing dramatic improvements in vehicle responsiveness and performance compared to the standard actuator, especially in the mid-range. In terms of value for money, the Turbosmart IWG-75 for the Focus RS is hard to beat. Additionally, its machined aluminum construction and Turbosmart's rigorous quality testing ensure maximum reliability, while the locking collar design allows for quick spring changes, should you wish to tune your Focus for increased turbo pressure.
