2015-2021 WRX 3-Port Boost Control Solenoid by Cobb

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 1/4" low-profile barb fittings to keep the unit compact and are nickel coated for corrosion resistance. 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.
