Turbo XS WS08-BCS 3-Port Boost Control Solenoid Kit for 2008-2021 Subaru WRX STI
$149.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2008-2021 Subaru WRX STI (including Base, Limited, S209, and Type RA).
The Turbo XS WS08-BCS 3-Port Boost Control Solenoid Kit is an essential upgrade for any EJ25-powered STI running increased boost levels. This kit replaces the factory 2-port bleed-style solenoid with a high-performance 3-port interrupt-style system. By converting to a 3-port configuration, you gain significantly more precise control over wastegate duty cycles, which is critical when installing an aftermarket downpipe or an upgraded turbocharger.
- Manufacturer Part Number: WS08-BCS
- Configuration: 3-Port Solenoid (Interrupt style)
- Replaces factory 2-port solenoid for superior boost mapping accuracy
- Recommended for vehicles with exhaust or turbocharger modifications
- Engineered for the 2008-2021 Subaru WRX STI platform
Precision boost control prevents overboost conditions and ensures your engine stays within safe operating parameters while maximizing power delivery. This kit includes the necessary hardware to integrate with your Subaru's factory wiring harness and vacuum routing.
