3 Port MAC Boost Control Solenoid (BCS)

The Full-Race 3-Port MAC Boost Control Solenoid (BCS) Provides Ultimate Boost Control

"After installing the Full-Race 3-Port, I have precise and repeatable boost control that wasn't possible with the OEM system. Boost fluctuations are a thing of the past."  — Cobb Pro Tuner Alan J.  

We engineered the Full-Race 3-Port BCS to be the top electronic boost control device for modern turbocharged applications, designed with outstanding boost control, engineered for consistent performance and extended service life, and configured for easy installation.

Get your boost under control and experience the power potential and tunability of your turbocharged vehicle with our new 3-Port EBCS! Full-Race's 3-Port Boost Control Solenoid (BCS) adds the flexibility and precision needed for properly controlling boost via the factory ECU. Many upgrades to the turbocharging system (big turbos and EWG) require the increased performance, reliability, flexibility, safety, and installation options that the Full-Race 3-Port BCS provides.

The Full-Race 3-Port BCS features Viton spools and seals throughout for long life. The manual override is sealed with an O-ring, the wiring harness is sealed to the casing using a waterproof grommet and the solenoid wires are ultrasonically welded to the coil, making the device waterproof and safe to wash. The BCS is rated to operate up to 120psi. Optional 1/8" low-profile barb fittings to keep the unit compact and are nickel coated for corrosion resistance are available for purchase.
