PRODUCT DETAILS ▾
RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed.
This is the GrimmSpeed Post MAF Hose Kit. This hose kit has been designed to replace the OEM hose to increase the flow to improve the overall power and response. This hose features durable 4-ply silicone construction that is heat resistant and features smooth interior walls that replace the corrugated folds of the OEM design. Additionally, this hose is flexible without affecting the structure to make this simple to install without the risk of collapsing under vacuum.
This hose also features tapered end portions making sure that the in er diameter will match the OEM air box and turbo inlet. A mismatched diameter will create steps that interrupt the airflow trajectories and will create small vortexes in the post-MAF hoses. Grimmspeed's design will prevent these issues.
SPECS:
- Red finish
- 4-ply stainless steel reinforced silicone construction
- OEM fitment
- CAD optimized design allows a seamless flow
- High-quality Breeze hose clamps
- No tuning required
- Gimmspeed logo
- Direct replacement for the factory hose
- Smooth interior walls allow for an unobstructed flow path of air
- Improves the throttle response and performance
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.
