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.

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.

Our special solenoid features, combined with our factory-fit brackets, ensure that this complete boost control solution will withstand the harsh heat and vibration of your engine bay. The Subaru harness connectors that we use include weatherproof terminal seals, carefully crimped with DELPHI equipment by our expert assembly staff. Mounting brackets are laser cut and then black zinc plated to ensure corrosion resistance. Each bracket has threaded PEM nuts pressed in for a solid connection with no risk of stripping threads. Each low profile 1/8" NPT nickel plated fitting is installed in the proper orientation using a 120psi thread sealant for a clean, compact, robust installation.

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 to ensure that you're building a setup that they're confident tuning. The good news is that with well over 25,000 units in use on some of the fastest Subarus in the world, with the GrimmSpeed Boost Control Solenoid, you'll be in great company. As with any change to your boost control system, upgrading to a 3-port solenoid does require tuning.

Features:

  • Decrease Spool Time - flows 10% more than the competition
  • Plug and Play into OEM Harness - no splicing wires like other BCS solutions
  • Works Safely with Factory Subaru ECU - custom coil to match ECU voltage
  • Nickel Plated Fittings - not the easily breakable plastic fittings!
  • 15min Installation - extremely simple with our written and video guides

Elegant with subtle tones
Color: Beige, Size: 5-panel
Well made, and rather elegant. It has more subtle tones in the weave than the picture can depict. Nice and lightweight so they are easy to move. Very lovely.

Pretty and useful
Color: Beige, Size: 6-panel
Bought this room divider as an alternative to installing a balcony shade and I'm so happy with it. It comes assembled and it's light to carry but stands firm once its placed. The bamboo material is a little sheer so the color gives the balcony a boho vibe. Very pretty way to block the sun and get some privacy.
