PRODUCT DETAILS
RallySport Direct carries highly engineered products designed to improve the performance and longevity of your vehicle brought to you by Radium Engineering.
These are the Radium Engineering Top Feed Fuel Rail Adapters. These adapters have been designed to work with the EJ253, as well as the JDM Ver 8/9 EJS207 intake manifolds, and permit the use of any OEM or aftermarket Subaru top feed fuel rail. Note that the slotted hole positioning on the adapters has been made specifically for the Subaru EJ253 intake manifold as moving the adapters outwards allows fuel rail fitment for the version 8/9 JDM EJS207 STI intake manifold.
HIGHLIGHTS:
- CNC machined billet 6061 aluminum construction
- Anodized and laser etched
- Designed to work with the EJ253, as well as the JDM Ver 8/9 EJS207 intake manifolds
- Permits the use of any OEM or aftermarket Subaru top-feed fuel rail
- Includes stainless steel hardware

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.
