Fits 2008-2014 Subaru Impreza WRX.

The Turbo XS 3-Port Boost Control Solenoid (BCS) is a direct-replacement upgrade for the factory 2-port unit. As owners increase power through aftermarket downpipes or upgraded turbochargers, the stock solenoid often lacks the precision and response time needed to maintain stable boost levels. This kit allows for much finer control, preventing boost spikes and tapering issues common on modified EJ-series engines.

By utilizing a 3-port design, this solenoid provides faster response and more consistent pressure management, making it a critical component for any custom-tuned WRX. This kit is designed for a clean installation and is intended to be used in conjunction with professional ECU tuning to recalibrate the wastegate duty cycles.

  • Replaces restrictive factory 2-port solenoid with high-response 3-port design
  • Essential for vehicles with upgraded downpipes or larger turbochargers
  • Provides precise boost management and improved wastegate control
  • Compatible with factory mounting locations
  • Manufacturer Part Number: W08-BCS
