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.

  • Custom Machined Adapter - Makes use of the factory turbo inlet recirculation port (instead of blocking it off), sealed with a VITON O-Ring
  • Black Anodized Finish - Protects the assembly from corrosion in an extremely demanding environment
  • 1/4" inch Barbed Fittings – Zinc plated and preassembled with anaerobic sealant; size matches the factory turbo and wastegate hose sizes
  • 3-Port Solenoid - Proprietary internal modifications prepare the solenoid for extreme automotive conditions
  • Plug-n-Play Wiring Connector - Plugs directly into the OEM wiring harness with no modification required
  • Compact Design - Mounts directly in factory location with the included adapter and zinc-plated steel bracket
  • Mounting bracket is laser cut and CNC bent from steel, and zinc plated; comes with stainless press-in nuts
  • Provides a quicker and more precise boost control response
  • Arrives fully assembled and ready for the installation
  • Tuning is required
  • Installation Guide

What's in the Box:

  • (1) Fully assembled 3-Port Boost Control Solenoid with Plug-n-Play Connector
  • (1) 1/4" inch hose, two feet long
  • Zip ties
  • All necessary installation hardware

Must Have Mod

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.

MUST HAVE!

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.
