DETAILS

Here, you are looking at the COBB Electronic Boost Controller for your 2015-2021 WRX. 

FEATURES: 

  • Accurate and Consistent Boost Control
  • Plug and Play 18-Gauge Wiring Harness
  • 1/4" Nickel Plated Barbed Fittings
  • Rated up to 120psi
  • Billet Aluminum Mount

    • CUSTOM TUNING IS REQUIRED!

    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 EBCS will eliminate boost fluctuations 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 1/4" low-profile barb fittings to keep the unit compact and are nickel coated for corrosion resistance. 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 installation and electrical connection as simple as possible. The BCS comes with a billet aluminum mounting block, 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 ultimate 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 installation.

    WHY?

    • The COBB 3-Port Boost Control Solenoid (BCS) adds the flexibility and precision needed for properly controlling boost via the factory ECU. Many upgrades to the turbocharging system (such as larger turbochargers and external wastegates) require the increased performance, reliability, flexibility, safety, and installation options that the COBB 3-Port BCS provides.

    Get your boost under control and Access the Potential of your turbocharged Subaru today!

    FITMENT NOTE: Will not fit some northern vehicles equipped with Subaru OEM cast aluminum turbo inlet.

    Subimods is best

    Honestly the cobb boost controller is slightly better quality than the grimmspeed, but both are very similar. I did have an issue with the nipple threading on the one I got but I reached out to subimods and they made it right and sent me a whole new one and the new one was flawless so I definitely recommend buying your parts from subimods when ya can.

    Zach,

    Still getting tuned but I can already tell the difference

    It's cobb, so of course the parts are well made instructions was easy and got to love the stickers always 😁

    Richard,

    Thank you for your 5 Star Review of the COBB Electronic Boost Controller for the 2015-2021 WRX! It is great to hear that you are already noticing a difference, even while still getting tuned. As always, COBB's well-made parts and easy-to-follow instructions are a big plus, and the stickers are a fun bonus. Enjoy the enhanced performance once your tuning is complete!

    Does what it should. 2015 WRX, combined with COBB Charge Pipe, BPV and Big SF Intake.

    It's built very well, was received quickly, and fitment was perfect. It's operating as expected. I can't really say much about the performance gains yet. I bought this to comply with COBB's NexGen Stage 2 + Big SF map, and while the car runs just fine, the map has actually reduced my performance from the Stage 1 + Big SF map. I'm going with a custom e-tune to try to make use of the various parts I've introduced. I also wish more of these came with installation instructions pertaining to the port connections. Everything is straight forward until it's time to connect the ports to turbo, wastegate and turbo inlet. COBB's website does have this information, so, in a pinch, check that out. That said, this is a quality product, and definitely more responsive than the OEM model.

    Brent,

    Thank you for your detailed review of the COBB Electronic Boost Controller for your 2015 WRX, along with other COBB upgrades. It is great to hear that the build quality, fitment, and speed of delivery met your expectations. Your insight into its performance and compatibility with COBB's NexGen Stage 2 + Big SF map is valuable information for other users. We understand your desire for more comprehensive installation instructions, and your recommendation to check COBB's website for additional guidance is helpful. We hope your upcoming custom e-tune brings out the full potential of your modified setup, and that you continue to enjoy the improved responsiveness this boost controller offers. Furthermore, we appreciate your 5 Star Review! Safe and exciting driving ahead!
