GrimmSpeed Boost Solenoid - STI 2008-2017
GrimmSpeed has introduced the most complete and easy-to-use 3-port electronic boost solenoid available on the market. This GrimmSpeed Boost Solenoid allows you to raise the OEM boost levels in a quick and efficient manner. If you try to raise the boost on the weak OEM boost solenoid, it will become unpredictable and unable to maintain stable and safe boost levels. Using this solenoid, you are able to spool your turbo much quicker and maintain a rock-solid boost level. GrimmSpeed has made this solenoid strong enough to withstand up to 120psi.

Revolutionizing the Subaru boost solenoid market, GrimmSpeed has created model-specific install brackets that allow you to directly fit this boost solenoid onto your Subaru for a factory fit. No more zip-tying! The GrimmSpeed Boost Solenoid gives you the factory fitment you have been waiting for.
Staying with the OEM fitment theme, this boost solenoid uses a Subaru-style wiring harness so you can simply unplug your OEM solenoid and plug in the GrimmSpeed unit. No more cutting the OEM wiring and crimping wires together!
For this unit, GrimmSpeed uses ultra low-profile hose fittings to keep it as small and clean as possible. The hose fittings are nickel-plated brass, so you don't have to worry about them snapping off like the OEM plastic hose fittings!
