Per our GM approved aftermarket upfitter who has a factory rep on staff: The reason the smaller filters are used is that the modern engine simply doesn't need a large one. The oil pressure is controlled in many designs now and the engine life is ridiculous if you simply care for the engine exactly as per the OLM. Our last engine failure occurred well past 200k miles. One of our service vans had half a million miles on the engine and was sold with no smoking, leaking, or any usage of oil.
A larger filter is a "feel good" mod with no proven benefit and some small risks...
