Should I get an oil cooler?

To answer you, Yes I do know the stock air intake is a Cold air intake that is why mine is still stock. But if my chemistry knowledge is correct heat transfers goes from hot areas to cold. Therefore, heat will transfer from the hot block to all surrounding parts whether you drove forward, backward or sideways. Our engine bays are packed so there isn't many places for that heat to go but other parts. The plastic intakes do better than metal but they still heat up. Along with the maf sensors.

I don't have the tools or time to make this study. But I would like to see a test done where temperature and humidity Are constants. And the person measures oil temperature vs air intake temperatures.

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.

spot on. I have the tools to do a test, which I did, oil temp doesn't have direct effect on engine performance. my car made the same power at 200 vs 270. just stick an electrical tape to the gauge and you won't think twice about it
