Tasked with controlling how much boost the Focus's turbo is allowed to produce, the wastegate plays an integral role in the turbo system. However, the Focus's standard actuator does not let the Focus reach its full potential, even at standard boost pressures.

OEM wastegate actuators tend to use soft springs, which begin to open long before peak boost is reached. The result is that you don't get all the boost you could be getting. Turbosmart's IWG-75 Internal Wastegate Actuator is a 14PSI-rated actuator designed with performance and reliability as key priorities. Turbosmart's actuator provides faster boost build-up and less drop-off at high RPMs, with a more responsive and stable boost curve.

The results of fitting a Turbosmart IWG to your Focus RS are truly impressive, giving you dramatic improvements to the vehicle's responsiveness and performance compared to the standard actuator, especially in the mid range. As a bang-for-buck modification, Turbosmart's IWG-75 for the Focus RS is hard to match.
