Product Description

The Perrin ASM-TAC-731 Pro Electronic Boost Control Solenoid is a direct bolt-in upgrade for 2008-2021 Subaru WRX STI models. It offers ultra-fast response and 50% higher flow than OEM units, thanks to a custom solenoid coil and valve.

Not CARB-approved, this is ideal for high-performance and racing applications.
