Because it is a cartridge, only the element is replaced at each service and the housing stays on the engine. Inside the housing, the Cummins 3937743 traps wear particles and soot before oil travels back to critical engine parts. Changing it on schedule keeps the lubrication system clean and reduces the waste of discarding a full metal canister.
