Just ace, as an example, dropping iat from 95 to 60c increases the density of the air at 20psi gauge pressure by 10%.
I remember an old autospeed article that claimed every 4c lower intake temp was worth 1%. So 40c lower intake temp in theory is worth around 10%, which lines up with the air density.
But the main thing is consistancy. A car that can keep its intake temps under control, allows a tuner to work out an accurate safety margin. Also intake manifold gaskets last longer, your intake valves, valve stem seals etc all last a lot longer.
But deco, 95c is a massive number. My efr 6258 heats the air up to 135c @ 20psi, but that is with the air temp sensor in the outlet pipe pre intercooler.
