Features & Product Details

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.

Higher than stock WGDC 1 month ago
mindriddle
You will read the disclaimer that this needs to be tuned to have lower than stock wastegate duty cycle of about 20-30% or else you will over boost. Well, mine is one of the few oddball ones where it is currently at 25% above stock WGDC to hit target boost and be responsive. At stock duty cycles, the car just felt sluggish and slow. Like others, I have checked connections and hoses a handful of times to make sure they are correct, which they are.

Better boost control 3 months ago
WRC fan
This is definitely a must-have part to support other power mods. For some reason, my WGDC's with the COBB boost control solenoid are pretty much the same as stock. After everything I read, I was expecting duty cycles to be lower than stock, but not the case. I double-checked and triple-checked the installation and hose routing, and it's all hooked up properly. Had to tune wastegate duty cycles around 55-70% to reach 18psi on 2012 STI with stock turbo, COBB downpipe, COBB SF intake, Tomei UEL headers. After some tuning, I can hit 18psi at 3400 rpm without spiking, and smoothly control it over the rev range. Caution- it's quite difficult to reach down to the wastegate actuator to remove the stock vacuum hose and install the new hose and zip tie. It helps to take off the top mount intercooler.

Cobb 3port boost controller selenoid  7 months ago
Ramy S
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 10 months ago

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!

      A:  You will need a pro tune for a boost controller. The OTS maps will not work with this.
