This CNC machined billet rail replaces the factory Honda D-series unit and runs a large internal bore so fuel delivery keeps up with higher injector flow. It is machined from 6061 aluminum, anodized, and laser etched, with four 8AN ORB ports: one at each end plus two auxiliary ports on the top face for a Radium fuel pulse damper, a regulator, or a gauge adapter. The injector bores are 11mm ID, the same as OEM, so factory injectors or any equivalent aftermarket injector seats correctly. Mounting follows the OEM locations, which covers every OEM D-series intake manifold and any aftermarket manifold that retains the stock rail mounting points.
