Grimmspeed 3-Port Electronic Boost Control Solenoid 2017-2021 WRX (Canadian Models Only)

This listing is specifically for the Canadian Spec 2017+ Domestic Market WRX with cast aluminum turbo inlet, instead of the composite inlet found on the USDM WRX. The cast Canadian inlet features a coolant passage that is not found on USDM composite inlets. This coolant passage occupies space that the traditional mounting of the GrimmSpeed EBCS also occupies. Our solution is a simple modification to how the EBCS is mounted to the inlet and a re-route of the hoses. These changes will not affect the functionality and will not differ from the composite inlet version of the EBCS.

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.
