Cobb 3-Port Boost Control Solenoid | 2015-2021 Subaru WRX (714750)

With fast shipping and good advise from MAP, my Cobb 3-way boost control is waiting for its cat-back exhaust before being installed.
Looks like another quality part from Cobb (I was disappointed it did not come with the screws that would fit Cobb turbo intake /and the squeeze claps do not fit the hose they supply).

First I’d like to say that MAPerformance has been the best place to order upgrades/aftermarket parts for my car.

21 WRX with COBB intake and catted TurboXS J-pipe/ 3” midpipe. Car was not able to run smoothly on any OTS tune(no reliable tuners in my area and it must be done in person and not over data logging/Etune). I installed the Cobb EBCS And Reinstalled stage 2 + BigSF tune. Let me just say it has been the most transformative upgrade. The car was boost spiking/overboosting (up to 24 psi)in hard throttle. Now it never goes over 22 and runs all the way up the limiter with no hesitation/pulling power by the ecu. The car used to get crazy fine knock learn from -9 and up. Now the worse I’ve had is a -1.05, I used to get -2.41 stock every single day. Now I barely get -1.05 with AC blasting at Wide Open Throttle. If you’re upgrading beyond the intake you will need one of these. Cobb was the easiest looking choice for install and wouldn’t require a full tune. Their stage 2 OTS maps all account for their EBCS installed.

a must have part that will provide great longevity and instant performance increase. would for sure recommend the COBB EBCS to anyone.

I bought this as my final piece to go Cobb nexgen stage2+
Install was fairly simple. I was a little upset that Cobb only gives you screws as if going ina oem inlet. So one thing to note; if you have the Cobb turbo inlet, you will need to remove the 2 little bolts holding in the factory ecbs and get them about an inch long. Hope this helps!

Hands down the best EBCS on the market!!! I made the mistake the first time buying the Perrin one and what a POS!!! don't waste your time on anything else.... buy it. All tuners prefer it over others.
