HOA 3 Port Boost Control Solenoid is a great alternative to a external boost system, 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 controllers.
This 3-Port Boost Control Solenoid, made in Germany, is a direct replacement on Subaru, Mitsubishi and other turbo vehicles 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 or Mitsubishi. We recommend using it only with hoses of the highest quality.
This German 3-Port Control Boost Solenoid is imported and distributed by HOA
