The change in temperature is going to cause both a change in volume and density the MASS will remain the same as read by the MAF, unless the pressure changes in which case density and volume could remain unchanged with the increase in pressure.
Mitco, while a plenum IAT sensor isn't very important as far as calculating fuel demand and air mass goes if you have the one in the MAF, timing and temp corrections for burn speed and injection angle are going to be effected greatly if there is an unmetered increase in air charge temperature.
