Features and Specifications
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 and boost creep 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 ulimate 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
