Looking at the part numbers, there were two designs for the air box and the connecting elbow on the discharge. Parts catalogs only differentiate between the filter being the K47 component, not the housing. The only difference appears to be that the first one was for the “Donaldson” air cleaner and the second version was for Delphi. Both used the same part number for filters.
The first one was 15998570 which is this one:
Second design, part number 19201265:
Searching parts sites, the first design comes up for all 1996 models, the second for all 1998 with both coming up for 1997. I would assume that there is some overlap, then.
If the K47 option really was just a different air filter, then GM made a damn killing when people checked that option box. Glancing at the specs for the two Delco air filters, the K47 is 20mm thicker. That’s it.
Standard filter:
High capacity (K47) filter:
