Cobb 3-Port Boost Control Solenoid 2008-2014 WRX/2008-2021 STI

The Cobb 3-Port Boost Control Solenoid (BCS) adds the flexibility and precision needed for properly controlling boost via the factory ECU. Many upgrades to the turbocharging system (such as larger turbochargers and external wastegates) require the increased performance, reliability, flexibility, safety and installation options that the Cobb 3-Port BCS provides.

Note : This product requires custom tuning 

If you are running an external wastegate setup you will need the upgrade kit.

• 2008-2021 WRX STI 
• 2005-2010 Legacy GT
