Description

An Elegantly-Engineered Solution.

The 2015-21 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.

The advantages of a 3-port boost control system vs. the factory 2-port are readily apparent during the tuning process. The 3-port systems work 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.
