Cobb Tuning 3-Port Boost Control Solenoid | Multiple Subaru Fitments (715750)

The COBB 3-Port Boost Solenoid (BCS) is an excellent upgrade for modern turbocharged vehicles, enabling precise boost control in a tidy package that is easy to install and tune. Our BCS will eliminate boost fluctuations inherent in the OEM boost control system, providing stable and repeatable boost control to base the vehicle’s tune on. It is equally capable of providing this stable boost control at stock boost levels as well as extremely high boost levels associated with big-power builds.

The COBB Tuning 3-Port BCS features 1/8″ low-profile barb fittings to keep the unit compact and are nickel coated for corrosion resistance. Optional 1/4″ nickel plated fittings are also available separately. Viton spools and seals are used throughout for long life and lubricated with Dow Corning silicone grease. 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.

COBB Tuning has made the COBB 3-Port BCS installation as simple as possible. It mounts in the stock location and plugs directly into the stock wiring harness, making the physical install and electrical connection as simple as possible. The BCS comes with a custom aluminum mounting bracket, stainless steel hardware, boost-line to complete all connections and zip-ties to route the boost-line neatly through the engine bay. Installation Instructions are provided, are easy to understand, and provide routing instructions for both internal and external wastegate configurations.

The COBB Tuning 3-Port BCS is engineered to be the ultimate 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 Access the Potential of your turbocharged Subaru today!

Warning! The installation of this 3-port solenoid requires proper tuning. The use of a COBB OTS map designed for a stock solenoid, with a 3-port solenoid installed, will result in drastic under or over boost behavior. Always match your tune with the exact components and installation method required for that tune. This includes how the hoses are routed to/from the EBCS, and which boost restrictor pills are present. If you have any questions or concerns and will be using an OTS map, please contact us. If you’ll be using a custom tune, talk to your Protuner about which EBCS and hose routing method they desire for your application.
