The point that I read is that the stock coolant journals throughout the engine don't pull enough heat off the oil, so this oil cooler provides a mechanism for getting that accomplished. And the idea is that spikes in temperatures in any one area (fluids, chambers) can lead to engine failure, so distributing the heat out will allow for safer engine use at high thresholds.

The other point is that this kit doesn't increase the thermal capacity of the system because there is no addition of cooling surface area. If heatsoak was an issue then a larger radiator would be necessary. In the case that the oil regulator couldn't extract enough heat, and it was a bottleneck in cooling (coolant temps were ok, oil temps were heat soaked) then a dedicated oil cooler would be necessary. The good thing is that OEM oil regulator could work in conjunction with aftermarket oil coolers with the addition of a sandwich plate like with the Mishimoto example. In either case, with a radiator or with an aftermarket oil cooler, the system has increased its thermal capacity through the addition of more radiators/cooling surface area.

would a termostat plate still be needed for cooler climates or would the oem setup keep the temps up?
