Interresting to note that the less "performance oriented" models from BMW use air-to-air intercoolers...
It is a question of specific heat properties of fluids. Water can store 3300 times the quantity of energy for one degree of temperature elevation by volume compared to air (about 4x by mass). You need a lot of "air heat" to heat soak a water system...
