Replace your cheap factory plastic oil squirters in your 89-02 Ram Cummins with these Aluminum Piston Oil Squirters from XDP. These are commonly known as piston cooling nozzles, cooling jets, or oil squirters. These are an easy and affordable upgrade for your Cummins engine build. Unlike the factory squirters that are constructed of plastic, these XDP squirters feature a 7075 aluminum construction with a larger orifice size to increase oil volume.
