Our 350z Fuel Rails are machined from billet T6061 Aluminum stock. The rail has a larger bore diameter then stock, allowing fuel flow to increase 350% more over stock (as seen above). The rail comes clear anodized to help protect against the elements. The rail is tapped to accept dash 6 fittings. Our rails are unique in the fact that you can either use your stock injectors or use taller aftermarket bosch style injectors to upgrade your fuel system. The rail comes with four dash 6 O-ring to dash 6 AN fittings, aluminum spacers to allow use with either style injectors, and stainless button head hardware.
