It threads into the engine block oil gallery and sprays a targeted stream of pressurized oil onto the underside of the piston, carrying away heat and reducing thermal stress to improve durability. You typically replace these nozzles during an engine overhaul or when a piston shows signs of overheating or scuffing, ensuring each cylinder gets proper cooling oil flow. It is a direct aftermarket replacement for the Cummins OEM nozzle 3080708.
