I've got a theory for you, mind you it's really out there.

Putting in a colder plug transferred more heat to the heads (valves in particular), the heated valves expanded more (lengthened) and closed the lash of the bucket-camshaft interface. Tighter lash meant quieter buckets and less false knock.
