Those look like the trumpet style horns Carnewal sells.

The dry ice is an interesting approach. I did it on a car and the price was about $750. Took a loooong time (almost a day) including set-up. It was painfully loud (literally painful - one should wear ear protection just to observe). Results were not as nice as these pix. If anyone is aware of a detailer in NorCal that does similar work for similar price please post info.

That thing on the oil cooler fan looks like an aftermarket alarm horn.
