Radium Engineering Fuel Rail Adapter – Ver8/9 EJ207, EJ253, EJ259

These billet adapters allow the installation of standard Subaru top feed fuel rails (including Radium 20-0577) onto specific non-standard intake manifolds, making them ideal for engine builds eliminating TGVs or using rare manifold configurations. Designed for flexibility, the slotted mount holes permit precise alignment for different EJ-series manifolds.

Compatibility:

• Subaru EJ207 (JDM Ver8/9 Manifold Only)

• Subaru EJ253 (Aluminium Manifold Only)

• Subaru EJ259 (All Versions – Legacy, Legacy GT, Outback)

Overview:
Ideal for custom Subaru EJ builds, these adapters make it possible to retrofit top feed fuel rails onto EJ253 and JDM EJ207 (Ver8/9) intake manifolds. The EJ259 manifold also benefits, offering a clean solution to replace the OEM tumble generator valve setup.

Key Features:

• CNC machined from billet 6061 aluminium

• Black anodised and laser etched for corrosion resistance

• Stainless steel mounting hardware included

• Slotted hole design for multi-platform fitment
