Fuel Injector and Sensor Assembly for the 2.5L six-cylinder M51 turbo diesel, part of the diesel fuel injection circuit. The assembly is supplied as the injector nozzle and holder complete with its integral needle-lift sensor and flylead. The sensor signals the point at which the injector needle lifts, giving the engine management system its injection-timing reference. The injector mounts into the cylinder head and is fed by the high-pressure delivery pipe from the injection pump. Show more
