The 1st gen dodge Cummins nozzles can really make your old girl perform like a new later model truck. Please note that the 1989-1991.4 engines were non-intercooled from the factory and have a 9mm bore in the stock head for the injector bore and requires the 9mm bore copper adapter to be able to install the newer 91.5-93 Bosch 7mm nozzles. Take note: PDR will not except 9mm Bosch nozzles as cores.
