Long term yes, but in high demand applications such as towing or racing, the cooling effect of the oil is needed. That's why you find oil coolers on race cars and tow trucks. The cooling system can only handle so much in either extended idle or WOT. In circuit races, the ambient air temperature on the track is higher than normal operating conditions, and the engines are built such that they create high amounts of heat. the oil coolers become necessary in those applications. For street use, I don't see a need in a Stang. Remote mount oil filter may be useful, but not an oil cooler.
