2015+ Subaru WRX 3-Port Boost Control Solenoid By Grimmspeed (057041)

The advantages of a 3-port boost control system vs. the factory 2-port system are readily apparent during the tuning process. The 3-port systems 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 GrimmSpeed's machined adapter. This is important, as the factory Mass Airflow 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 more slowly and with less precision. The addition of the GrimmSpeed BCS shows much tighter boost control and consistency. This is safer for your car and easier for your tuner.

057041 Features

  • 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
  • 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
  • 1/4in Barbed Fittings - Matches the factory turbo and waste gate hose size

Please Note:

  • Because this upgraded solenoid affects the way that your vehicle controls boost (that's the point!), 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.

GS EBCS Great Product!

The grimmspeed ebcs is a great product. It performs just as intended, helping tuners controller the boost levels for your WRX. The install is not bad at all. I highly recommend this part for anyone tuning their WRX as to not get any unwanted overboosting.

Install was pretty strait forward on my 2017 wrx maybe took an hour after fighting with the inlet and the bpv but after that it was smooth sailing
