buy original
Great quality heater, you can tell the difference between this and the Chinese copies. Just as a heads up make sure there’s no air in the lines before you turn it on

OEM Part
This is the same part that the Cummins dealer had for $375. Works great. The power cord on this unit was shorter than the old part, but a 3' extension cord solved that problem.
