The Original Direct-Fit BCS for turbo Subarus.

GrimmSpeed is proud to provide the most complete and easy to use 3-Port Electronic Boost Solenoid for available for all turbo Subarus. Unlike your OEM 2-port solenoid, the GrimmSpeed BCS will allow for extremely high resolution boost control, providing your tuner with the hardware he needs 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. In addition, our solenoid features a balanced valve to withstand up to 120psi without a slowing response by even a single millisecond.

Design

Revolutionizing the Subaru boost solenoid market, we have created model specific install brackets that allow you to install our Boost Control Solenoid with a factory fit and finish. To top it all off, our solenoid also uses a Subaru wiring harness connector so that you can simply unplug your OEM solenoid and plug ours in. No more cutting and crimping OEM wires together!

The solenoid itself is one of a kind. MAC manufactures pneumatic control products for the largest commercial operations in the world, where every minute of downtime can cost tens of thousands of dollars, so we worked closely with their engineers to design this unique valve, incorporating proprietary features, exclusive to GrimmSpeed, that make our solenoid the toughest on the market. Those features include special seals to protect it from moisture and high temp coils to keep response times at 6 milliseconds or less, even in extreme heat. We have worked with many of the top tuners in the country to ensure that our solenoid works safely with the factory Subaru ECU.
