Overview
The Perrin Electronic Boost Control Solenoid (EBCS) is engineered to optimize boost management for turbocharged Subaru engines, delivering faster spool-up and more precise boost control. Designed specifically for Subaru WRX, Forester XT, Legacy GT, and Outback XT models within the specified years, this solenoid is ideal for enthusiasts seeking improved throttle response and stable boost levels. Whether you’re tuning for street performance or track use, the Perrin EBCS offers a reliable upgrade over factory components.
Built around a custom-made solenoid coil and valve tailored to Perrin’s exacting specifications, this EBCS operates nearly twice as fast and flows approximately 50% more air than typical aftermarket alternatives. Its 3-port design enhances boost control resolution, allowing tuners to safely increase boost pressure while maintaining stability throughout the RPM range. The solenoid’s compatibility with OEM ECU calibrations means it reduces common overboost conditions without triggering check engine lights, preserving factory drivability.
For Subaru owners, this means a tangible improvement in turbo response and power delivery, especially when paired with a proper ECU tune. The durable 6061 aluminum construction ensures consistent performance under harsh under-hood conditions, making it a dependable choice for daily drivers and performance builds alike. The Perrin EBCS is a practical upgrade that unlocks your turbo’s full potential while maintaining the reliability Subaru enthusiasts expect.
