DETAILS

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. This 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.

  • Accurate and Consistent Boost Control
  • Plug and Play

(2004 WRX Wagon) Fixed my over-boosting, and my boost surging, and is just a really nice upgrade

I started getting some pretty consistent boost surging, and was getting over-boosting up to 19psi with a mostly stock setup. I traced this back to a little tear in the vacuum line between the compressor housing and the wastegate actuator, and instead of paying $40 for just that one hose (and maybe then running into other problems down the line since the rest of the system is 20+ years old), I decided to replace the whole boost control system with this COBB EBCS. Easy install, fixed both of the issues caused by the vacuum leak, and paired with the Stage 1+ EBCS OTS map, it runs like a dream.
