The owner of Volant use to be the tool guy for iceman intakes, they are set up just like the AEM kit long and short rams, Ice around the intakes is still around today same as CO2 spray, It all started from racing just like everything else
it was popular with the ricer crown about 10 years ago or so. It had a box right after the filter that you would load dry ice into so the air was cooler.... hahahaha hilarious!
