The Original Direct-Fit BCS for Subarus - Now for ANY Platform!

When it comes to boost control on turbocharged engines, GrimmSpeed Direct-Fit, 3-Port Electronic Boost Control Solenoids for Subaru, Mitsubishi and Mazda have set the standard in the industry. With that popularity, have come requests for additional fitments for other makes and models throughout the years. It is impossible for us to manufacture a direct fitment for every platform out there, so we've decided to offer a universal option for those who want the best 3-Port EBCS money can buy!

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 thousands of dollars. We worked closely with their engineers to design a valve specifically for automotive use, incorporating proprietary features exclusive to GrimmSpeed. Those features make our solenoids the toughest on the market and a tuner favorite for the last decade. This includes special seals to protect it from moisture and high temp coils to keep response times at 6 milliseconds or less, even in the extreme heat of your engine bay. We have worked with many of the top tuners in the country to ensure that our solenoid works flawlessly with factory or standalone ECUs.



  • Nickel Plated Fittings - 1/8 NPT to 5/32" barb fittings for easy line plumbing
  • 2 Mounting Brackets Included - Flexible mounting options to best suit your build
  • Bare Pigtail Harness - Easily crimp on whatever connector best suits your setup
  • Tuning Required - As with any EBCS, ECU tuning is required post-install


You don't need to take our word for it, trust your tuner. When it comes to boost control systems, be sure to consult with your tuner and make the choice to run the best boost control equipment available. With well over 50,000 units in use on some of the fastest Subarus in the world, the GrimmSpeed Boost Control Solenoid IS that best choice for a reason.
