Description

The COBB 3-Port Boost Solenoid (BCS) is an excellent upgrade for modern turbocharged vehicles. This compact design enables precise boost control 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 ¼” 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, and 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 120 PSI.

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, and boost-line to complete all connections and zip-ties to route the boost-line neatly through the engine bay. Installation instructions are provided, and are easy to understand and provide routing instructions for both internal and external wastegate configurations.

Cobb 3port boost controller selenoid

Everything came fast and as described the install was a little bit of a hassle but after doing some research it was a breeze. If you're not mechanically savy you're best bet is to take your car to a shop to peform the installation. DON'T FORGET YOU NEED A TUNE AFTER INSTALLING THIS PART!!!

A must for a protune

Whether you go with Grimspeed or Cobb you want your tuner to precisely set your target boost. I went with Cobb solely based on there name being associated with Subaru's. If your adding basic bolt on's such as intake, downpipe, up pipe, headers, tgv's deletes, etc make sure you add this to the list!

Another Awesome Cobb Product

Works well, easy to install.. If you can't install this, you may need help with life haha. It fits well under the stock cover so if the popo pops ones hood, they don't know anything is different :) Definitely tune your car after installing this. Works with the big boy turbos as well. Currently in use on a 13 STi with a Blouch Dom 1.5xt-r, no issues!

  • Q: Overboosting  Dangerdan 4 years ago

    Answer

    I currently have Cobb stage 2 set up and while going WOT in 3rd or 4th gear my car will overboost and throw a CEL and a code P0244, will this combined with a protune eliminate the issue?


    • A: If you are using a catless downpipe, then that would most likely be the issue. Changing to a catted downpipe should fix the overboosting. If you are indeed using a catted downpipe, then this should be a good solution.

  • Q: Only used for a stage 1 or stage 2?  Frank Stepanski 4 years ago

    Answer

    Should this be used for only a tuned car? Not stock tune?


    • A: When installing this you will want to get a custom tune.
