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!)

Not eczema skin friendly
Size: 5.5 Ounce (Pack of 1), Size: 5.5 Ounce (Pack of 1)
Since I didn’t remember which sunblock spray I had previously purchased (that was super awesome), I got this one with a few other ‘kid’ sunblock spray and stick. I had grabbed this one for a splash pad birthday party this weekend only to find out it’s messy and not eczema skin friendly. Either we got a defective bottle or it’s just the way it sprays: runny goops of sunscreen that takes awhile to dry properly (see photo). And when it dries it really does stick onto your skin as advertised (aka not breathable, pore clogging, will irritate sensitive/eczema prone skin). My youngest has eczema prone skin (that’s been flare up free for 3 years) had a severe break out on her arms after using this. And even for the sake of photo demonstration for this post my own sensitive skin got red/irritated. So does it stick-yup. Is it messy? Definitely. Easy to apply? No (your kiddos have to stay put until it dries). Did it provide sun protection? Maybe…? Sensitive skin friendly? No. Eczema skin approved? Definitely not. Recommended? Nope. We threw it away and requested a refund.

10/10 sunscreen spray
I have combination skin that can get oily throughout the day, and I was excited to try the Naked Sundays SPF 50 Golden Glow Shimmer Setting Spray because I loved the idea of having sunscreen and a setting spray in one product. The first thing I noticed was the packaging. The ombre gold to purple container looked so luxurious and intentional. The spray mist was fine and even, making it perfect to apply over my makeup with a smooth finish. I love the scent. It smells fruity and delicious, which is such a refreshing change from the typical sunscreen smell that many other sunscreen sprays have. Overall I loved this spray and it exceeded my expectations. It kept my makeup looking fresh all day long and gave my skin a beautiful, glowing finish. I would definitely recommend and I will 100% be purchasing it again!

Easy Spray Sunscreen with No Greasy Hands & No Harsh Smell
Really impressed with this sunscreen. The spray nozzle makes it incredibly easy to apply without getting my hands greasy, which is a huge plus. It feels lightweight on the skin and doesn’t leave a sticky or heavy residue. One thing I loved is that it doesn’t have that typical strong sunscreen smell, it’s much more subtle and pleasant. I’ve also worn it during workouts, and it didn’t run into my eyes or cause any stinging when I was sweating, which is rare for me. It layers well over makeup and gives a nice, subtle glow without looking greasy. Overall, it’s convenient, mess-free, and something I’ll definitely keep using for easy SPF reapplication throughout the day.

Nozzle doesn’t work on a $30 sunscreen!!
I’d give this zero stars if I could. While I imagine the glow is amazing, I wouldn’t know because the spray nozzle on this doesn’t work. Not a single spray. I’m assuming it’s clogged with glitter and I’ve tried everything unclog it but for $30, I shouldn’t need to decant or switch this into another bottle. I will end up doing that, so I can hopefully use it, but my complaint remains. It is also not eligible for returns or replacements. Cute but useless packaging.

My Favorite SPF Setting Spray
The Naked Sundays SPF 50 Golden Glow Shimmer Setting Spray gives the prettiest glowy finish while making SPF reapplication so easy. It feels lightweight, doesn’t mess up my makeup, and adds the perfect touch of radiance without looking too glittery. Definitely a staple in my routine!
