GRIMMSPEED BOOST CONTROL SOLENOID - 08-20 STI
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.
