Pierburg 3 Port Boost Solenoid 15+ WRX

Unlike the factory solenoid,this 3-Port Solenoid allows you to raise the factory boost levels with more response and adding more control.

With this solenoid no boost pressure is allowed through to the actuator so no premature boost can occur. The 3-Port Solenoid allows lower wastegate duty cycle to produce higher boost pressures with much greater control,thereby allowing tuners more “headroom” and “space” when modifying high horsepower turbo vehicles.

The kit includes the 3-Port Boost Control Solenoid and harness for plug and play install with Subaru 2015+ WRX and Brackets to make it for easy Plug and Play application.

Tuning Notes:

Because this upgraded solenoid affects the way that your vehicle controls boost, it is always recommended that you consult with a tuner immediately following installation. It is not recommended that you drive the car in a way that builds boost without doing so. If you have any questions, don't hesitate to get in touch with us directly!
