The Subaru Impreza 2.5i (EJ253) and JDM Ver8/9 (EJ207) intake manifolds are great solutions for eliminating the tumble generator valves on modified engines.
These Radium Engineering adapters permit the use of any OEM or aftermarket 2002+ Subaru top feed fuel rail (such as Radium 20-0479) 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 EJ207 intake manifold.
