Cobb 15-21 Subaru WRX 3-Port Electronic Boost Control Solenoid
The Cobb 3-Port Electronic Boost Control Solenoid (PN 714750) is a direct replacement for the factory 2-port solenoid on 2015-2021 Subaru WRX models. It enables faster turbo spool-up, accurate boost holding up to 40 PSI, and reliable performance under high-demand conditions. Pair it with ECU tuning for noticeable gains in throttle response and power delivery.
Key Features
- Plug-and-Play Design: Bolts directly into the OEM location using factory brackets and connectors no cutting, splicing, or modifications required.
- 3-Port PWM Control: Provides precise electronic actuation for consistent boost levels, far beyond the stock solenoid’s 20 PSI limit.
- Durable Brass Construction: Features a robust brass body with stainless steel internals to withstand heat, pressure, and repeated cycling.
- Fast Response Time: Quicker solenoid opening and closing reduces lag, improving turbo efficiency across the RPM range.
- High-Pressure Capability: Safely manages boost up to 40 PSI, supporting tuned setups with larger turbos or higher targets.
Product Notes
- ECU tuning required (Cobb Accessport recommended) to fully utilize and map the solenoid’s capabilities.
- EPA compliant for on-road use designed for street and track applications.
Installation Notes
- Professional installation recommended.
- Access solenoid from underside near turbocharger 30-60 minutes with basic tools.
- Compatible with OEM vacuum lines and mounting hardware torque to factory specs.
