Features & Product Details

The Grimmspeed 3-Port Electronic Boost Solenoid has been a treasure to the turbocharged world of sport compact drivers. one of their best selling items here at RallySport Direct is their easy to use 3-port Electronic Boost Control Solenoid. This particular boost control solenoid will allow the use to raise the OEM boost levels in a quick and efficient manner. Trying to raise the boost on the weak OEM solenoid can become unpredictable because of its inability to maintain proper and safe boost levels. By using the Grimmspeed unit you are able to improve boost response while maintaining a solid and consistent boost level. And it's also super durable as Grimmspeed has crafted this solenoid to withstand 120psi which is much more than your engine will be able to see. 

One of the greater aspects of this boost control solenoid is that Grimmspeed designed these to have model specific brackets, as well as OEM connectors. This means that you can bolt the bracket right up to the factory solenoid provision and plug it right into the factory plug to be a direct fitment plug and play unit. this eliminates the need for wire splicing or using zip-ties that could potentially create a visual eyesore in the engine bay. 

Grimmspeed also made it a point to use ultra-low profile hose fittings to keep the unit as small and compact as possible. The hose fittings are made of nickel plated brass so you don't have to worry about breaking the factory plastic hose fittings.  

Full features include:

•    Direct plug and play into OEM wiring
•    MAC completely custom made valve
•    Users can use AN fittings with the solenoid
•    Mounting bracket so it’s a direct bolt-on into factory location
•    Low-profile brass hose fittings (small in size so its compact)
•    Specifically designed by GrimmSpeed to work safely with the factory Subaru ECU (requires tuning) and to reliably handle the vibrations and temperatures on your engine bay
•    The only direct “bolt in” design for all Subaru models. Direct bolt-in mounting bracket and hardware included
•    Includes plug and play harness, no wire splicing required, and easily can be returned back to stock
•    Allows you to raise the factory boost levels with adding more response and more control
•    Allows you to get to full boost sooner
•    Faster response and greater flow than any other valve out there. (By more than 10%)
•    Nickel plated brass fittings

The GrimmSpeed Boost Control Solenoid is easy to install, just plug and play. And it looks SO much better than the OEM unit.

Good choice 3 years ago
5out of 5stars

I was torn between this and a Cobb boost controller for my 07 WRX. I got this because of my tuner's preference. The car needed tuning to use this, but I got injectors at the same time, and so it was and I'm happy. I would buy this again. As a note, Cobb and Grimmspeed are both vendors I have used before and that I would recommend.

06 STI 3 years ago
5out of 5stars

My 2006 STI needed to be pro tuned so I decided to get an aftermarket EBCS. I really like Grimmspeed products so I decided to go with their EBCS. I was not disappointed. Quality is amazing as always and with the instruction video that they make for all their products, it was easy to install. The only thing I wish they would do different is provide silicone vacuum tubing. It does come with plan rubber vacuum tubing though. I changed out all my vacuum lines with Turbo Smart tubing while I was in there.

I decided to get my car pro tuned so I bought the Grimmspeed BCS to go along with it. It works great! Part is awesome quality as always with Grimmspeed, I just wish it came with silicone vac line instead of just rubber line. Other than that I love it. Easy install too!

QUESTIONS & ANSWERS

  • Q: 08+ wrx GS boost control solenoid   Fn2187wrx5 months ago

    Hello, I just had a GS 3 port boost control solenoid put on my 2011 wrx. Unfortunately, I will not be able to get the pro tune done for a couple of weeks. Is it okay to drive my car while I’m running an OTS Cobb stage 2+ tune and the boost control?
    • 0 of 0 people found the following answer helpful

      A:  Just don't go into boost. Basically drive it like you're braking in a brand new engine. Thanks.

  • Q: Grimspeed Ebcs fitment question   Greg P. 10 months ago

    Hey RSD - I purchased a grimspeed ebcs for 08+ wrx not knowing I got the sti version. Will the sti version work on my 2013 wrx? Is it a fitment issue , or an internal issue if it doesn't work ? Thanks, Greg
    • 1 of 1 people found the following answer helpful

      A:  You'll want part number GRM057032 for your WRX. Although the solenoid itself is similar, the one specific to your vehicle will be the safest and simplest route.

  • Q: Bcs  De Daddy 1 year ago

    Hey their can i use this with the Cobb accessport stage tunes ?
    • 0 of 0 people found the following answer helpful

      A:  Cobb only has Accessport tunes that work with an EBCS for a couple of select models, and they will be specific to Cobb's BCS. All other tunes that do not specify will technically be specific to the stock boost controller.

  • Q: Grimmspeed 3 port ebc  04BlobEyeSTi2 years ago

    I think my GS ebc solenoid crapped out on me.. if this was to happen and I replace it with the same GS 3 port would I need retune? I've heard it would have the same tune I had since it's the same brand/model boost controller
    • 0 of 1 people found the following answer helpful

      A:  If it is the same exact boost controller and you can set it to the same exact parameters you would not need to retune.
