CAI .... Cold Air Intake

[ainarssems]

Well you cannot get air cooler than ambient without some type of active cooling(something like extra high power aircon for intake) but that would not be practical and possibly rob more power to operate it that you would gain. Another option would be nitrous injection.

47p2 picture shows fuel cooler which is mounted in intake, that would make intake air even hotter as it cools down fuel.

Stock A/S8 already have 'cold air intake' as does all modern cars drawing air from the front of car unlike some old cars that used hot air from under the bonnet.

Well known 'tuning' is to put resistor in place of air temperature sensor to fool ECU of thinking it gets colder air and to inject more fuel at WOT and advance ignition.
