PRODUCT DETAILS
RallySport Direct proudly carries a great selection of quality performance upgrades by our friends over at GrimmSpeed.
This is GrimmSpeed's new Direct Fit, 3-Port Electric Boost Control Solenoid. This is a one-of-a-kind unit that was co-developed closely with MAC's engineers to design a valve specifically for automotive use, and it incorporates proprietary features that are exclusive to GrimmSpeed. These features make their solenoids the toughest and most robust on the market and a tuner favorite for the last decade. This includes special seals to protect it from moisture and high-temp coils to keep response times at 6 milliseconds or less, even in the extreme heat of your engine bay. GrimmSpeed has worked with many of the top tubers in the country to ensure that their solenoid works flawlessly with factory or standalone ECUs.
HIGHLIGHTS:
- Nickel Plated Fittings: 1/8 NPT to 5/32" barb fittings for easy line plumbing
- (2) Mounting Brackets Included: Provides flexible mounting options to suit your build
- Bare Pigtail Harness: Easy crimp-on to what connector will suit you best with your setup
- Tuning Required: After post-install, tuning will be required
- Highly durable
- Very fast responding
- Provides optimal boost response and boost control
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
