GFB 7301 WGA Internal Wastegate Actuator EVO 4-8 Adjustable Turbo

The GFB 7301 WGA (Wastegate Actuator) is a high-performance bolt-on replacement for the factory internal wastegate actuator on Mitsubishi Lancer Evolution models 4 through 8. Engineered to overcome the limitations of stock actuators, this precision-machined upgrade delivers improved boost control and more consistent turbocharger performance.

Key Features:

• Direct bolt-on installation for EVO 4-8 turbochargers - no modifications required
• Larger diaphragm design provides more force and faster response compared to factory actuator
• Adjustable base spring pressure from 5-22 PSI allows precise boost tuning
• High-quality construction ensures reliable operation under extreme heat and pressure
• Eliminates boost creep and improves boost stability across the RPM range
• Allows you to maximize your turbo's performance potential without upgrading to an external wastegate

The WGA actuator is an essential upgrade for modified EVOs running higher boost levels, providing the precise control needed to safely extract maximum power from your turbocharger system. The adjustable spring pressure accommodates everything from mild street setups to aggressive track builds.
