If you've been in the Subaru game for long, you're probably well aware that a 3-port Boost Control Solenoid (BCS) is considered by most to be a 'must have' upgrade before having your car tuned. GrimmSpeed has become the most trusted brand in the BCS market, with tens of thousands of their boost control solenoids in operation today across the globe.

The 2015+ WRX offers a unique change of pace, as the OEM 2-port solenoid is mounted directly to the plastic turbo inlet and interfaces with an o-ring rather than a vacuum hose. With expertise in designing and machining their tried and true boost control solenoids, GrimmSpeed was excited to dig in and create a boost control solenoid for the 2015+ WRX that continued their proven pedigree of high performance and quality.

 

The advantages of a 3-port boost control system vs. the OEM 2-port system are readily apparent during the tuning process. The 3-port system works by interrupting the boost signal traveling from the turbo to the wastegate. That boost is redirected back into the turbo inlet and re-ingested by the turbo using the machined adapter. This is important, as the factory MAF Sensor has already measured that air and is expecting that your motor will use it during combustion, rather than venting it to the atmosphere. The factory configuration simply 'bleeds' the signal from between the turbo and wastegate, which creates a system that is a bit less complex, but reacts much more slowly and with less precision.

 

The GrimmSpeed Boost Control Solenoid has been proven time and time again. With tens of thousands on vehicles across the world, tuners trust it and customers love it. What you see here is the same great solenoid with millions of miles of real world testing and an innovative mounting solution, designed specifically for your 2015+ WRX. The machined adapter also features standard NPT threads, should you choose to upgrade to AN lines and fittings, or even a different boost control solution (manual, standalone, hybrid, etc) down the road. The GrimmSpeed BCS system arrives fully assembled and ready for installation.

 

Because this upgraded solenoid affects the way that your vehicle controls boost, it is always recommended that you consult with a tuner immediately following installation. It is not recommended that you drive the car in a way that builds boost without doing so.
