WGA Internal Wastegate Actuator - Adjustable

• 2004–2021 Subaru | WRX STI
• 2002–2026 Subaru | WRX

Massive performance, compact size. The GFB WGA internal wastegate actuator features an industry-first diaphragm design — the silicone/Nomex diaphragm uses a new bead retention design that achieves the largest effective area with the smallest possible outside diameter. This keeps the overall size of the WGA down whilst giving it more control authority over the wastegate flap, resulting in better boost control.

• Silicone/Nomex diaphragm with bead retention design
• 18mm of rod travel — suitable for the largest internal wastegates
• Compact size with more control authority over the wastegate flap
