Matches my turbo inlet very nicely!
I can’t wait to get this thing on the car and tuned in!

Fitment Information:
2015-2021 Subaru WRX
Please note: Will only fit with the factory composite turbo inlet.
Features:
The advantages of a 3-port electronic boost control solenoid (EBCS) vs. the factory 2-port system are readily apparent during the tuning process. The 3-port systems works by interrupting the boost signal traveling from the turbo to the wastegate. That boost is redirected back into the turbo inlet and re-ingested by the turbo using our machined adapter. This is important, as the factory Mass Airflow Sensor has already measured that air and is expecting that your motor will use it during combustion, rather than venting it to the atmosphere. The factory configuration simply 'bleeds' the signal from between the turbo and wastegate, which creates a system that is a bit less complex, but reacts more slowly and with less precision.
The dyno chart above shows two boost plots. The 'before' is our 2015 WRX, dyno tuned by a third party protuner. The 'after' is the exact same tune, but after the installation of the GrimmSpeed 3-Port BCS. As you can see, the addition of the GrimmSpeed BCS shows much tighter boost control and consistency. This is safer for your car and easier for your tuner.
An elegantly engineered solution.

Part fit perfect ! Do not use any of your old parts only what’s supplied and also a set of extra rubber tubing would be great in case you cut the tube supplied to short making 290 on 91 pump gas with ebcs tmic charge pipe cai turbo inlet and nameless bpv
Works great and easy install, a must have for all tuning purposes
This is just simply the best EBCS you can get. Highly recommend. Import Image made the order and delivery experience perfect as well.
Bought this to replace my Perrin ebcs. Much better product!
If you are looking to tune your car this is the best bang for your buck. Get the Inlet duct as well as the BPV and do everything at once.
If your think about going 3 port just do it. This for sure is more accurate boost controller it really started feeling way better and smoother into boost.
I'm getting my car tuned on the 1st and my tuner recommend to get the grimmspeed boost control solenoid. Build quality is great. And have heard nothing but great things about this product. Fast shipping as always. Thank you import image racing.
This was insanely easy to install! Definitely noticed a difference in boost! After my tune, my boost felt more consistent and responsive! This is definitely one of those mods I recommend getting first if you want a noticeable difference in power.
