I read out of an automotive book that for every 1000-ft of elevation, your car loses 3% performance relative to sea level. BUT does anyone know numbers when it comes to air temperature??
(Assuming that the car does not have forced induction)

for air temperature, colder is better. that’s because cold air is more dense, so if you put cold air into a cylinder, you could fit more molecules than if you put in hot air. that’s why when people tune their cars, they put in cold air intakes because they pick up air from a cooler area under the hood instead of around where engine sits.

and just if you were wondering, a car at higher elevations performs worse because the air is less dense, so less air molecules entering the cylinder.

Not much really.
