Perrin Electronic Boost Control Solenoid 2002-2007 WRX / 2004-2007 STI

The custom made solenoid coil and valve are made specific to PERRIN specs. This allows the valve to operate almost 2 times faster, flow almost 50% more than competitors' designs. The EBCS Pro also works with OEM ECUs without causing check engine lights. To fully utilize the EBCS Pro, an ECU recalibration is NEEDED to ensure no overboosting occurs.
