CNC machined from solid 6061 aluminum, anodized and laser etched, this rail has two 3/4in-16 (8AN ORB) end ports and three injector bores for the YXZ's three cylinder engine. It is compatible with all fuel types including E85 and works with factory or equivalent injectors. It mounts to the throttle body housing on new supplied screws rather than the two OEM screws and spacers. Radium notes that when running Injector Dynamics injectors, the OEM lower cushion takes the place of the Bosch EV14 lower O-ring and retainer.
