Perrin Electronic Boost Control Solenoid 2008-2021 STI | Fast Response | Precision Boost Management
Overview
The Perrin Electronic Boost Control Solenoid (EBCS) is a high-performance upgrade designed specifically for the Subaru WRX STI models from 2008 to 2021. This solenoid replaces the factory unit to provide more precise and faster boost control, enabling enthusiasts to unlock the full potential of their turbocharged engines. Ideal for tuners and performance drivers, the EBCS improves spool-up times and allows for higher, more stable boost levels throughout the RPM range.
Engineered with a custom coil and valve built to Perrin’s exact specifications, this solenoid operates nearly twice as fast and flows approximately 50% more air than typical aftermarket alternatives. Its 3-port design offers superior control resolution compared to OEM units, making it a reliable foundation for advanced tuning setups. The durable 6061 aluminum construction ensures consistent performance even under the demanding conditions of spirited driving and track use.
Compatible with OEM ECU calibrations and popular engine management systems such as COBB Accessport and open-source tuning platforms, the Perrin EBCS reduces common overboost issues without triggering check engine lights. This makes it an essential upgrade for Subaru WRX STI owners seeking improved boost stability, quicker turbo response, and safer power delivery. Note that an ECU calibration is required to fully leverage the benefits of this solenoid.
