PRODUCT DETAILS
RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed.
This is the GrimmSpeed MAF Block-Off Plate. This plate has been designed for users that have upgraded to the blow-through system, and need a clean alternative to blocking off the old MAF provision location. This is a great way to provide a proper seal for the old MAF location while improving the overall aesthetics of the engine bay.
DETAILS:
- Durable aluminum construction
- Anodized black finish
- Etched GrimmSpeed logo
- Designed for users converting to the blow-through-system
- Covers the MAF provision location
- The bottom of the plug has been contoured to match the intake piping for unobstructed air flow
- Includes a durable O-ring for an air-tight seal
- Includes new installation hardware
- Sold individually
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.
