Features:

The GrimmSpeed Boost Control Solenoid is the most complete and easy to use 3-Port Electronic BCS. Unlike your OEM 2-port solenoid, the GrimmSpeed BCS will allow for extremely high resolution boost control at elevated boost pressures, providing your tuner with the hardware needed to safely tune your car with rock solid boost levels. Using our solenoid, you are able to spool your turbo quicker and maintain tight control of boost levels throughout your power curve, allowing you to run the max safe boost at any point in the rev range. In addition, our solenoid features a balanced valve to withstand up to 120psi without a slowing response by even a single millisecond.

  • Decreases Spool Time - flows 10% more than the competition
  • Plug and Play into OEM harness - No cutting or splicing!
  • Model-specific bracket for a clean install
  • Works safely with the factory Subaru ECU
  • Nickel plated fittings are included
  • Tuning is required
  • Installation Guide

Nice quality part

Plug and play what more can you ask for? hardest part was getting the tiny hoses on the waste gate titter. other than that easy peasy. This should help my boost issues the stock one wasn’t cutting it anymore.

Boost controller

Really good product with extremely fast shipping from import image. This boost controller accurately helps tuner gauge accurate boost numbers that your car is putting down versus the OEM boost controller.
