Features & Product 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.

Easy install, high quality materials 7 months ago
Installed this with other mods on my Evo X to match the Stage 3 OTS requirements. Install as easy, just follow the instructions (1 bolt, and 3 hoses). But make sure you load the proper map or get a pro tune, as the instructions state. The OTS Stage 3 map specifies you must use this EBCS, but the instructions say not to use it, so it's a little confusing. I am using it with the stage 3 map, no major issues thus far, but will likely get a pro tune in the near future to be safe.

Awesome! 3 years ago
I have an accessport, but I was getting crazy boost spike with a stage 2 OTS map. I installed this along with the other parts needed to run a stage 3 map. No more boost spike! I'm at a solid 26 pounds right now!

  • Q: stg2 to stg 3 access port  mbeam4 years ago

    If im running a stg2 off the shelf map what would be the increase in power if any with the bcs w/stg3?
    • 1 of 1 people found the following answer helpful

      A:  The power increase may not directly come from the solenoid itself but more so the tune that is necessary to properly run a Electronic Boost Control Solenoid.
