The wastegate actuator is a crucial component in controlling how much boost your Focus RS’s turbocharger can produce. The factory wastegate actuator uses a soft spring, which often begins to open before peak boost is reached, limiting the turbo’s potential even at standard boost pressures.

The Turbosmart IWG-75 Internal Wastegate Actuator is engineered specifically for the Focus RS, featuring a 14 PSI-rated spring for improved performance and reliability. This actuator delivers faster boost build-up, reduced boost drop-off at high RPM, and a more consistent, stable boost curve compared to the OEM unit.

Constructed from billet materials and tested to Turbosmart’s rigorous quality standards, the IWG-75 offers excellent durability. The locking collar design allows for quick spring changes, making it easy to fine-tune your Focus RS for higher boost levels if desired.

If you’re looking to enhance your Focus RS’s responsiveness and mid-range performance with a straightforward, reliable upgrade, the Turbosmart IWG-75 Internal Wastegate Actuator is a top choice.
