GrimmSpeed 3-Port Boost Control Solenoid (Part #57046)

If you're a proud owner of a 2015-2021 Subaru WRX or 2010-2012 Subaru Legacy GT, you know that performance tuning is essential for getting the most out of your ride. The GrimmSpeed 3-Port Boost Control Solenoid (BCS) is a game-changer for those looking to enhance their vehicle's boost control and overall performance, especially if you're planning to tune your car.

Why Upgrade to a 3-Port Solenoid?

The stock 2-port solenoid on the 2015 WRX is mounted directly to the plastic turbo inlet, which can limit your options if you’ve upgraded to an aftermarket turbo setup. GrimmSpeed has designed this solenoid with flexibility in mind, providing a universal mounting bracket that allows for easy installation regardless of your turbo configuration.
