GFB WGA Internal Wastegate Actuator – Mitsubishi Evo X (CZ4A)
Application: Mitsubishi Lancer Evolution X (CZ4A) 2007–2015
Part Type: Internal Wastegate Actuator (WGA)
GFB has built a reputation for turbo boost control components that punch well above their size, and the WGA internal wastegate actuator is no exception. Designed to replace the restrictive factory actuator, it gives your Mitsubishi Evo X sharper throttle response and a far more stable boost curve, without the bulk of a typical aftermarket unit.
This listing covers the Mitsubishi Evo X (CZ4A), 2007 to 2015, fitted with the factory turbocharger. SKU 7303 is a direct bolt-on replacement designed specifically for this platform.
Important: This is a tuning component, not a straight bolt-on upgrade. Fitting the WGA will raise boost pressure above factory levels, so a professional retune is required afterwards.
Key Features
- Nomex-reinforced silicone diaphragm for maximum control authority in a compact housing
- 18mm (0.7 in) rod travel — longest stroke in its class for extra tuning range
