HOA Imports 3-port boost control solenoid
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.


3 – Port Boost Control Solenoid and Harness


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 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 plug and play install with Subaru or Mitsubishi. We recommend using it only with hoses of the highest quality.

Commonly asked questions:

The HOA Imports 3 port boost control solenoid is a direct replacing on Subaru and other turbo vehicles. It is a direct replacement for the stock Subaru 2 port boost control solenoid, it does not place additional load on the Subaru ECU electronics.

The H.O.A Imports 3 port boost control solenoid is primarily designed to be used with EcuTek tuning software, this high-end software package allows full access to the necessary waste gate control parameters in the stock ECU, this enables very fine boost control and minimizes premature waste gate opening.

The HOA Imports 3 port boost control solenoid is also of benefit to consumers who have aftermarket ECU’s that use the factory (or similar) boost control solenoid.

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

We recommend fitting the HOA Imports 3 port boost control solenoid in the stock factory location on the Subaru turbo vehicle, using the harness provided for easy direct fitment.

We recommend using the HOA Imports 3 port boost control solenoid only with hoses of the highest quality, depending on the parameters set in the ECU it is easily possible to see excessive or even uncontrolled boost should hoses fail.
