AUTHORIZEDGrimmSpeed offers one of the best 3 port boost control solenoid kit's (ebcs) for the 2015+ Subaru WRX FA20 platform. The advantages of a 3-port boost control system vs. the factory 2-port 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 our 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 GrimmSpeed EBCS provides much tighter boost control and consistency, is safer for your car, and easier for your tuner to work with when tuning your car. This kit comes with everything needed for the installation including 2 feet of 1/4" hose, zip ties, and all necessary hardware.
Note: Installing this product will require a custom calibrated tune for your car to run safely.
