Perrin Electronic Boost Control Solenoid 2015-2021 WRX / 2014-2018 Forester | Faster Response | Precision Boost Control
Overview
The Perrin Electronic Boost Control Solenoid (EBCS) is engineered to optimize boost management for turbocharged Subaru engines, specifically the 2015-2021 WRX and 2014-2018 Forester models. Designed for enthusiasts seeking precise control over turbo boost pressure, this solenoid improves spool-up times and reduces overboost conditions without triggering check engine lights. It is ideal for those running ECU calibrations who want to unlock the full potential of their turbo setup with reliable and consistent boost control.
Built around a custom solenoid coil and valve designed to Perrin’s exact specifications, this EBCS operates nearly twice as fast and flows approximately 50% more than typical aftermarket solenoids. The 3-port design enhances boost response and control resolution, allowing tuners to safely increase boost levels while maintaining stability throughout the RPM range. Its durable 6061 aluminum construction ensures it withstands the harsh under-hood environment, reflecting Perrin’s commitment to quality and performance.
For Subaru owners, this solenoid translates to improved throttle response and more predictable turbo behavior, especially when paired with a proper ECU tune. The plug-and-play design fits directly with factory connectors and mounting points, making it a straightforward upgrade that complements popular engine management systems like COBB Accessport. This precision boost control solution is a practical step for WRX and Forester drivers aiming to enhance their turbocharged driving experience.
