Pierburg 3 Port Boost Solenoid (Subaru all models)
Pierburg is one of the biggest names in Europe and have made these 3 port boost solenoids for PRODRIVE.
for the likes This 3-Port Boost Control Solenoid, made in Germany, is a direct replacement on Subaru and it does not place additional load on the ECU electronics.
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. We recommend using it only with hoses of the highest quality.
