Cummins 4910355 Aftercooler Core

The Cummins 4910355 aftercooler core is a direct-replacement charge air cooler core engineered for Cummins K19, KTA19, and QSK19 engine platforms. It functions as the heat-exchange element within the aftercooler assembly, reducing compressed intake air temperature from the turbocharger before it enters the engine cylinders. Constructed from aluminum or copper alloy with tube-and-fin or bar-and-plate architecture, the core provides high thermal transfer efficiency under continuous heavy-load operation. It is designed to withstand typical charge air pressures up to 3.5 bar and inlet temperatures up to 200°C. The core interfaces with OEM aftercooler housings and piping via standard flange or hose-bead connections per Cummins installation drawings. Cross-referenced OEM part numbers include 3001299 and 206807. Applications span on-highway heavy-duty trucks, off-highway construction machinery, marine propulsion, power generation, and pump-drive configurations utilizing the K19/KTA19/QSK19 engine family.
