CPL= Critical Parts List
It is the designation Cummins uses to identify specific engine component configurations. It can be found on the dataplate on the rocker cover.
It includes; (I don't know the complete list)
-injectors
-pistons
-turbo
-DPF

An engine can be interchanged with a used, reman, etc. with the same CPL, and installing the correct software (AV# for an 871) version.
Two engines with the same CPL's have the same hardware components, but not necessarily the same programming.
That's why I assumed the CPL would include either single or dual element oil coolers.
