This is the four cylinder rail for the Prostar 2.0L, CNC machined from solid 6061 aluminum, anodized and laser etched, with three 3/4in-16 (8AN ORB) end ports and four injector bores. It takes factory or equivalent injectors and uses the injector clips, and it is compatible with all fuel types including E85. Unlike the Prostar 900/1000 rail it needs no mounting brackets: it bolts to the intake manifold reusing the four OEM mounting screws, which makes it a short job with an 8mm socket.
