go fast bits boost controller spares, g-force 4-port solenoid (inc 4 hosetails)

Designed for use in applications which target a clearly defined boost curve Capable of improved boost response The 4-port design works equally well in low boost applications as it does in high boost setting When controlling your boost is essential, then turn no further then the GFB G-Force 4-Port Boost Control Solenoid. This brand new innovation from GFB blows the world of boost solenoids out of the ball park in both reliability, quality and performance. Differs from a traditional 4-port Boost Control Solenoid because it precisely directs pressure to the open and close ports of your waste-gate diaphragm. This allows much lower waste-gate spring pressure for better low gear boost control and perfect high gear, high boost control. This GFB G-Force 3-Port Boost Solenoid includes all 4 hose tails that you need for install making this an awesome upgrade for all turbo cars requiring this type of Solenoid.
