Radium Engineering Fuel Rail Adapter - Subaru (EJ207 / EJ253 / EJ259)
These Radium Engineering billet adapters (SKU 20-0372) allow standard Subaru top feed fuel rails, including Radium's, to be fitted to specific non-standard intake manifolds. The Impreza 2.5i (EJ253) and JDM Ver8/9 STI (EJ207) manifolds are popular choices for eliminating the tumble generator valves (TGVs) on modified engines, and the adapters also suit the EJ259 manifold.
Slotted mounting holes provide adjustment: the standard position suits the EJ253 manifold, and moving the adapters outwards gives fuel rail fitment on the JDM Ver8/9 EJ207 STI manifold. The adapters are CNC-machined from billet 6061 aluminium, black anodised and laser etched, with stainless mounting hardware.
Note: Fuel rails are not included. Compatibility is by intake manifold: EJ207 (JDM Ver8/9 manifold only), EJ253 (aluminium manifold only) and EJ259. Confirm your manifold before ordering. Installation by a professional is recommended.
