"Better flow" when it relates to oil filters means less delta-p across the filter at the same flow rate.Well then maybe less restriction, or perhaps reduced bypass action?
If the positive displacement oil pump is not in pressure relief, then the same flow has to go through the oil filter regardless of filter restriction (delta-p). Yes, a more restrictive filter will have a better chance of going into bypass, depending on the filter bypass setting, and the oil viscosiy and engine RPM.
