GrimmSpeed Boost Solenoid - WRX 2006-2007 / STI 2004-2007 / Forester XT 2004-2008
GrimmSpeed introduces the most complete and easy to use 3-port electronic boost solenoid available on the market. This GrimmSpeed aftermarket boost controller 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 start to become unpredictable and unable to maintain proper and safe boost levels. Using this solenoid you are able to spool your turbo quicker and maintain a rock solid boost level. GrimmSpeed has made this solenoid to withstand up to 120 PSI.
Revolutionizing the Subaru boost solenoid market, GrimmSpeed has created model-specific install brackets that allow you to directly install the GrimmSpeed Boost Solenoid onto your Subaru for a factory fit. No more zip-tying! GrimmSpeed has given you the factory fitment that you have been waiting for.
Staying with the OEM fitment theme, the 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!
Also new to the Subaru boost solenoid market, GrimmSpeed has used ultra low-profile hose fittings to keep the unit 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 plastic hose fittings!
