Subaru WRX Boost Solenoid - COBB - 3-Port - 08–12 is a precision boost-control upgrade for 2008–2012 WRX and select STI models. It replaces the factory unit for accurate, repeatable turbo control.

COBB’s 3-port lets the ECU command the wastegate with more authority than stock, sharpening response and helping reduce spikes and oscillation. Built to handle under-hood heat, it delivers steady, predictable boost and supports custom calibration when properly tuned. A great choice for enthusiasts seeking reliable boost management as builds progress.
