If you've been in the Subaru game for a long, you're probably well aware that a 3-port Boost Control Solenoid (BCS) is considered by most to be a 'must-have' improvement before having your car tuned. GrimmSpeed has become the trusted brand in the BCS market, with tens of thousands of solenoids in operation today across the globe.  The 2015 WRX offers a unique change of pace, as the factory 2-port solenoid is mounted directly to the plastic turbo inlet and interfaces with an o-ringed feature, rather than a vacuum hose. With expertise in designing machined parts and a tried and true boost control solenoid, we were excited to dig in and create a solution with an already proven pedigree of high performance and quality.

- Custom Machined Adapter - Makes use of the factory inlet recirculation port, instead of blocking it off
- Black Anodized Finish - Protects the assembly from corrosion in an extremely demanding environment
- 1/4in Barbed Fittings - Matches the factory turbo and wastegate hose size
- 3-Port Solenoid - Proprietary internal modifications prepare the solenoid for extreme conditions below the vehicle
- Plug-n-Play Wiring Connector - Plugs directly into the factory wiring harness with no modification required
- Compact Design - No need to mount the solenoid elsewhere in the engine bay, increasing complexity and hose length
