GFB WGA high-performance internal wastegate actuator. It has a larger diaphragm area than the OEM actuator for better control of the wastegate flap, plus a longer stroke, shorter height and turnbuckle preload adjustment. Base boost is adjustable from 5 to 24psi with the supplied springs.

• 5psi and 10psi springs pre-installed for 15psi base; 7psi spring supplied

Includes: actuator, rod/clevis with nuts, bracket (where required), 3 springs

Fits:

• Subaru Impreza STI MY99-00
• Subaru Impreza STI MY03-07
• Subaru Impreza STI MY08-13
• Subaru WRX STI 2014-22 (EJ25)
• Suits most single-scroll IHI VF turbos. Does not suit factory twin-scroll turbos (e.g. Spec C Type RA)

This actuator WILL increase boost pressure, so tuning is required. Intended for racing use only. GFB recommends fitting by a qualified automotive technician.
