dont know if it would fit one with aircon, but auto doesnt make a difference. in fact thinking about it im 99% sure aircon doesnt matter either cos the guy i used to work for had aircon and im pretty sure his was the same size. im sure someone will confirm though.
i dont know what the measurements are because its at my mates garage, but it is the standard sized one rather than the larger one, so has no adverse impact on cooling cos it fits in the standard slot.
