GrimmSpeed Boost Solenoid Subaru WRX 2006-2007 / STI 2004-2007 / Forester XT 2004-2008

The GrimmSpeed aftermarket boost controller allows you to raise the
OEM boost levels in a quick and efficient manner.  The OEM solenoid is
programmed to make only so much boost, so surpassing the levels on the
OEM solenoid can become dangerous as the target numbers become
unpredictable, and dangerous for your motor.  With the GrimmSpeed
solenoid, you are able to spool your turbo quicker, and maintain a
consistent boost level.  These solenoids are made to withstand 120 PSI,
which is way more boost than any Subaru should see. 
GrimmSpeed provides model specific install brackets that allow you to
directly fit the GrimmSpeed Boost Solenoid into your Subaru for a
factory fit, so this eliminates zip ties, or sloppy installs. Because of
the OEM-style fitment theme, the Boost Solenoid uses a Subaru style
wiring harness so you can simply plug in your GrimmSpeed unit in place
of the OEM unit. And this eliminates the need for cutting or crimping of
the wires. 
These solenoids will also come with nickel plated brass fittings so
you don’t have OEM style plastic hose fittings that were prone to
breaking off.
