Clean Injection MAC Electronic Boost Control 3 Port Solenoid for 2015-2020 Subaru WRX
Up for grabs is Clean Injection MAC electronic boost control solenoid for the 2015-2020 Subaru WRX. Designed using well known and reliable MAC pneumatic 3 Port valve. MAC solenoid features high resolution boost control allow the the user to tune with rock solid boost levels. This 3 port solenoid will allow the turbo to spool quicker and maintain boost levels throughout the full power curve. NOTE: Upgrading to a 3-port solenoid will require ECU tuning.
The 3-Port Advantage
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 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.
Why MAC Boost Solenoids?

The MAC Boost Control Solenoid has been proven time and time again. With tens of thousands on vehicles across the world, tuners trust it and our 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 vehicle. 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. Finally, the Clean Injection BCS system will arrive fully assembled and ready for installation.
