The  MOST COMPLETE AND BEST PERFORMING MazdaSpeed BCS Ever Built, Period.

GrimmSpeed MazdaSpeed 3 3-Port Electronic Boost Control Solenoid
  • (Flows 10% more than competition) Get into Boost Much Quicker


  • Plug and Play into OEM Harness
    (no splicing wire like other BCS!)

  • Factory Fit for clean install

  • Works Safely with Factory Mazda ECU
    (custom coil to match ECU)

  • Nickel Plated Fittings as this is Built To Last
    (not the easily breakable plastic fittings!)

  • Easy to Install and Very Easy to Tune

  • The Only Direct Bolt-IN BCS for MS3


The GrimmSpeed™ MazdaSpeed3 Boost Control Solenoid is designed to work with your factory computer (requires tuning). It will not reduce the life of your factory computer because it is designed to draw the same ammount of power as the factory BCS but flows better and reacts faster. It plugs in and requires no splicing or soldering of resistors. With the included bracket you can bolt it in, plug in the connector, and start tuning for fast boost response, increased boost pressure and free up lots of power. Planning on returning the car to stock? Just reverse installation.

Why run an Electronic BCS over a Manual Boost Controller?
A MBC allows you to run higher than stock boost levels by preventing the wastegate from opening at its rated pressure. It does a great job at this but if boost is available under the MBC setting it will give you that full boost. So for instance, you set your MBC to 18psi because from 3000-6000rpm thats what you want. But then say you get detonation with 18psi when you are at 7000rpm unless you are below 16psi. With a MBC, you do not have this control so you are forced to run 16psi through the entire rev range. With an electronic boost controller you could run 18psi from 3000-6000 and 16psi at 7000rpm because you can tune the boost map in the ECU which will allow you to run the maximum amount of boost at every given rpm. This gives you more power throughout the range and better control. Revolutionizing the boost solenoid market, we have created model specific install brackets that allow you to directly fit our Boost Solenoid into your MS3 for a factory fit. No more Zip-tying! We give you the factory fitment you have been waiting for.

Staying with the OEM fitment theme, our Boost Solenoid uses a Mazda style wiring harness so you can simply unplug your OEM solenoid and plug ours in. No more cutting the oem wiring and crimping wires together!

Also new to the Mazda boost solenoid market, we have used ultra low-profile hose fittings to keep the unit as small and clean as possible. The hose fittings are nickel plated brass so you don't have to worry about them snapping off like the plastic hose fittings!

More Features:

  • Users can use AN fittings with the solenoid.
  • MAC Valve has completely custom made the valve for us(only MAC valve on the market to be custom made for automotive tuning use).
  • Specifically designed by GrimmSpeed™ to work safely with the factory Mazda ECU (requires tuning) and to reliably handle the vibrations and temperatures of your engine bay!
  • Direct bolt in mounting bracket and hardware included!
  • Faster response and greater flow than any other valve out there. (by more than 10%!)
  • Nickel plated brass fittings. (unlike the competitors failure prone plastic fittings)

    Solid

    Posted by Unknown on May 2nd 2019

    - shipping was on time (2 day air)
    - replacement for broken oem ebcs nipple
    - was able to attach to my JBR 51r small battery tray (left old ebcs in place)
    - hose lines were long enough to cut and reach from said location
    - running in 2 port mode (everything comes included to do this)
    - using the small oem clamps for hoses (even tho it says not necessary)

    - positives
    - boost is much more responsive
    - easy install

    - negatives
    - wish the two end bolt holes were actually closed loops. They're open ended and the bolts are held in place by rubber that can come out. would allow for more modular install locations but not a problem.

    - overall: 10/10

    even better with a good etune

    Posted by Mazdarrari on Jan 25th 2015

    My speed 3 was boost spiking like crazy with the stock ebcs. As soon as I changed to the GS ebcs and had it tuned, the car performs even better! Boost kicks in even faster now.

    boost kicks in faster

    Posted by Omar Gutierrez on Feb 13th 2014

    Easy to install, boost kicks in faster Than with oem BC. I installed this as a 2 port EBC so fluctuation boost still continues although is more stable now(boost stays closer to target boost). Over all very happy with product quality, easy to install, and great performance.

    Quick/Steady boost! Easy install

    Posted by Dewey G on Nov 25th 2013

    I was forced to upgrade the EBCS after breaking the plasctic nipple on the stock part. I have to say even in 2-port stock mode, this thing makes a world of difference. No more 1st-3rd limited boost, holds boost from idle to redline, and it spools quick! Very easy install, took about 20min all in. Thanks to the boys at Egde for the quick ship and great pricing as well.

    Broke my oem ebcs replaced it with this

    Posted by Unknown on Jun 18th 2013

    Hard to compare oem to this one as I drove a month with a broken oem one, but my ms3 feels like it spools faster from what i remembered. Easy install and fast shipping.
