Adjustable Internal Wastegate Actuator for Mitsubishi Lancer Ralliart

The GFB WGA 7300 Internal Wastegate Actuator is engineered to improve boost control on turbocharged Mitsubishi Lancer Ralliart models. Factory actuators can struggle to keep the wastegate closed under increasing exhaust backpressure, leading to boost taper and inconsistent boost delivery.

Improved Wastegate Control

A stronger actuator provides greater control over the wastegate flap, helping maintain target boost pressure more consistently across 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 bolt directly in place of the factory wastegate actuator using original mounting points. No fabrication or modification is 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.
