If you've been in the Subaru game for long, you're probably well aware that a 3-port Boost Control Solenoid (BCS) is considered by most to be a 'must have' improvement before having your car tuned. GrimmSpeed has become the trusted brand in the BCS market, with tens of thousands of solenoids in operation today across the globe.
The 2015 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, they were excited to dig in and create a solution with an already proven pedigree of high performance and quality. Other 3-Port boost control solutions don't facilitate the proper use of the turbo inlet's recirculation port. This product will allow existing owners of other boost control solutions to adapt their system and utilize that port properly.
They began by recreating the factory turbo inlet and solenoid in CAD to ensure a perfectly fitting system. From there, they designed a beautifully fitting machined adapter that would recreate the o-ring sealing feature that the factory solenoid uses. This bracket features 1/8 NPT threads so that both barbed fittings (included) and AN fittings can be used interchangeably, for use with the GrimmSpeed BCS, Manual Boost Controller, or other boost control solutions.
