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

  • Get into Boost Much Quicker
    (Flows 10% more than competition)

  • 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)

Easy for your shop or tuner to tune!(Engine tune is required!)

A hydrating sunscreen but won’t provide the coverage
I’ve been using CeraVe sunscreen, so that’s my baseline. It’s thicker, slightly pigmented, and very hydrating.. Switching to Eucerin felt like moving from a cozy blanket to a light sheet. It’s definitely thinner and less pigmented, so at first it didn’t give me that same immediate glow or coverage I was used to. That said, on its own, it’s still a good sunscreen. It spreads easily, feels comfortable, and does the job without heaviness. After using it for a while, I’ve kind of settled into a rhythm: • If I want a bit of coverage and that hydrated, supple finish → I reach for CeraVe • If I just need straightforward sun protection → Eucerin works perfectly fine One small downside is the packaging. The pump is convenient, but toward the end, I can already tell there’ll be product left that’s hard to get out since you can’t really squeeze or open it easily. Overall, I’d say Eucerin is a solid, lightweight sunscreen. Just don’t expect that tinted, slightly “makeup-like” effect if you’re coming from something like CeraVe. It’s more of a quiet, reliable everyday option than a multitasking one.

Ok for sunscreen
Works fine as sunscreen. Did make me look a little red but might be a reaction as I have very sensitive skin. Didn't notice any color change so basically it's just sunscreen.

Great sunscreen that feels light on skin
Great sunscreen that matches my skin tone and is very light. Its not makeup and also doesn't leave any white sunscreen residue. I can have sensitive skin when it comes to sunscreen and this is very gentle on my skin. Highly recommend!
