Radium Engineering Secondary Fuel Rail - Kawasaki Ninja H2 / Teryx H2 2015+

The secondary rail mounts to the intake plenum rather than the throttle bodies, and feeds the H2's four secondary injectors. It is CNC machined from solid 6061 aluminum, anodized and laser etched, with four injector bores machined for 11mm upper injector O-rings and 8AN ORB end ports. It is compatible with all fuel types including E85. The four OEM secondary rail screws are not reused; new screws are supplied with the rail.
