The Nuke Performance’s newest generation of fuel rails grants an easy fit to your engine with an extremely lightweight design. It uses the unique injector safety clips that fuel rails from Nuke Performance have become famous for, which grant a leakproof seal even during a crash where the fuel rail would get torn out of the intake manifold. For the BMW M10 and S14 engines, we do not provide you with the needed brackets for your installation, custom brackets need to be manufactured by the installer, and the fuel rail is equipped with two mounting points with M6 threads.
