you're correct in that the ambient air sensor is mounted in front of the radiator, but what you're not accounting for is that the IAT temperature is taken at the MAF sensor. thats the sensor in your intake tubing just before the throttle body. it is completely normal for the temperature to be higher than the ambient air because the air needs to travel from the intake hole by the radiator all the way up the tubes and measured.

when your car is running, the temperature difference will be significantly higher as there will be some heat soak from your engine
