In terms of aiding the cooling with an electric device I suppose you could do it with a Peltier device, also known as thermoelectric (TE) modules, these are small solid-state devices that function as heat pumps. A "typical" unit is a few millimeters thick by a few millimeters to a few centimeters square. It is a sandwich formed by two ceramic plates with an array of small Bismuth Telluride cubes ("couples") in between. When a DC current is applied heat is moved from one side of the device to the other

If you has an alloy intercooler and mounted the peltier to the end tanks perhaps this would work however the warm side of the peltier would obviously increase under bonnet termpratures..

Just mentioning theory, not for a moment suggesting that this would work or that Im going to try it
