MAC - 4 PORT - BOOST SOLENOID KIT

MAC 4-Port Boost Solenoid Kit – Maximum precision for high-end boost control

The MAC 4-port boost solenoid is the ultimate choice for advanced turbo applications that require added precision and wastegate control. Particularly useful with external wastegate systems, the 4-port design allows for more aggressive and faster boost regulation without the need for a high-pressure spring.

A complete kit is offered that includes the original MAC 4-port solenoid and the corresponding electrical connector with pins , ready to install.

🧰 Installation recommendation:

It is recommended to mount as close to the wastegate as possible for faster response. For proper adjustment, the ECU must support 4-port boost control logic. PWM frequency between 15–30 Hz depending on the ECU and application. Use quality hoses resistant to heat, pressure and oil.
