Ford Focus RS Internal Wastegate Actuator by Turbosmart Upgrade your Ford Focus RS Wastegate Actuator and increase efficiency and boost of your turbocharger. OEM wastegates tend to come with soft springs, which begin to open long before peak boost is reached. This causes you to not get all the boost that you could be getting. Turbosmart's IWG-75 Internal Wastegate Actuator is a 12PSI-rated actuator designed with performance and reliability in mind. This actuator provides faster boost build-up and less drop off at high RPMs. This in turn gives you a more responsive and stable boost curve.Installing a Turbosmart IWG to your Ford Focus RS is one of the best bang for your buck mods that you can do. The results are truly impressive with dramatic improvements to the vehicles responsiveness compared to the stock set up.
