If you've been in the Subaru game for long, you're probably well aware that a 3-port Electronic Boost Control Solenoid (EBCS) is considered by most to be a 'must have' improvement before having your car tuned. GrimmSpeed has become the trusted brand in the EBCS market, with tens of thousands of solenoids in operation today across the globe.
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. The chart above shows two boost plots. The 'before' is our 2015 WRX, dyno tuned by a third party protuner. The 'after' is the exact same tune, but after the installation of the GrimmSpeed 3-Port EBCS. As you can see, the addition of the GrimmSpeed EBCS shows much tighter boost control and consistency. This is safer for your car and easier for your tuner to work with.

Before you install it, you think: ah, who needs a 3port Boost Controller. I'd rather have something shinier.
Then, you put it on anyway, and your tune wakes up. It comes alive and the car just gets so much more fun to drive.
Install with the video is super easy (but don't mistake the coolant line for the boost one, I accidentally did that not paying attention. Coolant does not taste good). Pro-tip: definitely use the zip ties that come with it and put them on loosely before installing the tubes. Just makes it so much easier to get them where you want for a snug seal after installation.
Great part, definitely recommend to anyone looking to go to a stage 2 or above, or wake up their current tune. Made a huge difference and you wouldn't think it by looking at it, but it did.
