Adjustable Internal Wastegate Actuator for Mitsubishi Evo X

The GFB WGA 7303 Internal Wastegate Actuator is engineered to improve boost control on Mitsubishi Evo X models by replacing the factory actuator with a stronger, more adjustable design. Factory actuators can struggle to keep the wastegate closed as exhaust backpressure increases, leading to boost drop-off.

Improved Wastegate Control

A stronger actuator provides greater control over the wastegate flap, helping maintain target boost pressure more consistently through the rev range.

Adjustable Preload

The threaded actuator rod allows preload to be set accurately, making it possible to fine-tune boost behaviour for stock or modified setups.

Direct Bolt-On Fitment

Designed to install directly in place of the factory wastegate actuator using the original mounting points. No fabrication or modification required.

Tuning Required

Although this is a mechanical bolt-on component, it functions as a tuning tool. Installation will increase boost pressure, therefore ECU tuning is required.
