The Turbo XS WS02-BCS Boost Control Solenoid Kit for a 2002-2007 Subaru Impreza WRX EJ20 is designed to replace the factory 2 port boost solenoid. This 3 port boost solenoid control kit is required for greater and more precise boost control on your WRX when modding especially when using an aftermarket downpipe or upgraded turbo.
