Should I get an oil cooler?

I understand trying to apply logic and reason to a hypothesis.

The problem here is, the engineering and observed data don't jive with your hypothesis Yes heat transfers, but the rate of transfer is vastly different across different materials and states of matter.

Heat soak isn't going to occur to the point of pulling significant timing. Simply measure IAT from a readout to see exactly what is going on. If you are stuck at a stop light for a few minutes, IAT may creep up a few deg F but once you start moving its back to ambient. The intake is not hanging on top of the block.

The thermodynamics here are not much different from car to car. Air temp is going to matter to fuel/timing. If folks buy an oil cooler with the expectation its going to improve performance on a street car, I think that's a misinformed purchasing decision.
