You're going to facepalm when I tell you:

"in addition to" covers both type and quantity.

I can also point to the 2010 Inspection Checklist, page 2:

Only KoP Motors – 5 CIM, 2 Denso Left, 2 Denso Right, 2 Fisher Price, and 2 Mabuchi. <R52.A,D,E>

By some funny coincidence, that matches up with both the KOP checklist and the rules mentioned in the checklist item.
