I can give you another reference point. Our stock 182 always used the 48110 and
the Cessna oil filter adaptor, until the last overhaul, when the adaptor was
replaced with the latest version, and the filter changed to a 48108. At least,
the shop put a sticker on the firewall, warning "Use only filters with an internal
relief valve".
So there are other adaptors that need the 48108 filter.
