2015-2021 WRX 3-Port Boost Control Solenoid by Cobb

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. Our BCS 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.

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

Please Note: Requires Tuning

Applications

  • 2015 - 2021 Subaru WRX

Cobb 3 port

Easy, breezy, beautifully installed.

Great!

Good and solid. High quality silicone vacuum hoses. MAPERFORMANCE always ships with speed. Put this in last night. Pretty easy install. 1 thing I would've liked from COBB, would've been metal hose clamps. COBB included 4 small zip ties for both ends of ports 2 and 3. So close to the turbo. I will check them every oil change. Tune day today!

Cobb 3 port is awesome

Cobb 3 port from MAP arrived very quickly and communication was great. Followed cobbs instal and it was fairly easy. After tuning this part steadies the delivery of boost. A great addition for my build.

Big improvement

I bought this and had a local shop install it then pro tune my wrx. It made a huge improvement on day to day drive ability. If you get a j pipe I would recommend the boost controller and a pro tune.

Essential mod for tuning

I wish I had gotten this initially for an etune. Consistently holds boost with minimal erratic spiking. And MAP delivered it super quick!
