Radium Engineering's top‑feed fuel rail adapter bracket set is CNC‑machined from aluminum to permit use of Radium top‑feed fuel rails on compatible Subaru intake manifolds. It supports SUBARU EJ207 (JDM Ver8/9 manifold only), EJ253 (aluminum manifold only) and EJ259 (all versions), enabling the 20‑0577 style top‑feed rails to be mounted where those manifolds are used.
