GFB 4-Port Boost Control Solenoid - Universal
GFB has built a solid reputation among Australian tuners for electronic boost control gear that holds up to real world abuse, and this 4-Port Boost Control Solenoid is the replacement valve behind their most popular controllers. Based on the MAC 45 series design, it's the industry go-to for automotive boost control thanks to its rugged construction and consistent switching under heat and vibration.
This listing covers the standalone solenoid (SKU 3845), sold separately for use with GFB's G-Force II, G-Force III, and D-Force electronic boost controllers. It suits both single and dual solenoid setups where a spare or replacement valve is needed, and works across any turbocharged application already running a compatible GFB controller.
Note: This solenoid is a component part for GFB electronic boost controllers only — it is not a standalone boost controller and must be paired with a G-Force or D-Force unit to function.
