COMPATIBILITY
SUBARU EJ207 (JDM Ver8/9 Manifold Only)
SUBARU EJ253 (Aluminum Manifold Only)
SUBARU EJ259 (All Versions)
The Subaru Impreza 2.5i (EJ253) and JDM Ver8/9 (EJ207) STi intake manifolds are great solutions for eliminating the tumble generator valves on modified engines.
The rare EJ259 (shown below) is found in the Legacy, Legacy GT, Outback, and Legacy Outback. It has a 3-piece manifold with tumble generator valves in the center section.
These Radium Engineering adapters permit the use of any OEM or aftermarket Subaru top feed fuel rail (such as Radium 20-0577) to be used.
The slotted hole positioning below is specifically for the Subaru EJ253 intake manifold. Moving the adapters outwards allows fuel rail fitment for the Ver 8/9 JDM EJ207 STi intake manifold.
