PRODUCT DETAILS ▾
RallySport Direct carries highly engineered products designed to improve the performance and longevity of your vehicle brought to you by Radium Engineering.
This is the Radium Engineering Early Fuel Rail for the 4G63. This fuel rail has been designed with a larger internal bore to increase the fuel volume going into your factory, or aftermarket fuel injectors. A great modification as well for those of you with larger injectors operating under a built fuel system that needs no flow obstructions under operation.
HIGHLIGHTS:
- CNC machined from solid 6061 aluminum
- Anodized and laser-etched for a high-quality surface finish
- Manufactured with a large 0.69" internal bore that can support all necessary engine power requirements
- Compatible with all fuel types including popular alcohol mixtures such as E85
- Eliminates the OEM 2-bolt inlet flange which uses a restrictive 0.22" (5.7mm) orifice
- Features (4) threaded ports that are tapped for 8AN ORB
- All (3) ports use -8AN ORB threads
- Compatible with factory, or OEM equivalent fuel injectors
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.
