GrimmSpeed Electronic 3-Port Boost Control Solenoid Only Subaru WRX 2015-2021 | 057046 GrimmSpeed

Fitment Information:

2015-2021 Subaru WRX with aftermarket turbo ONLY

Please note: This solenoid is for use with aftermarket turbo kits only. Thus, it does not include the required adapter for the stock FA20 turbo inlet. It is NOT for use with the stock turbocharger, or other stock replacement turbos for the 2015-2021 WRX.

Features:

The advantages of a 3-port electronic boost control solenoid (EBCS) 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. 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 BCS. As you can see, the addition of the GrimmSpeed BCS shows much tighter boost control and consistency. This is safer for your car and easier for your tuner.
