or to a Manual Boost Controller. This solenoid is a direct OEM replacement, that includes
a Plug and Play harness (no wiring needed). This solenoid is controllable via Stock ECU,
when being pro-tuned using the stock ECU. This Solenoid, unlike stock, will control boost
well beyond 40PSI, and will help with boost creep that is common with manual boost
This 3-Port Boost Control Solenoid, made in Germany, is a direct replacement for
Subaru's and 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 wastgate 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 a plug and play
installation. We recommend using it only with hoses of the highest quality.
