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.
The main reason for "poor" performance is the low octane fuel. Try with 100+ octane fuel. With 91 or 93 octane you have too much detonation, and ECU is correct advance timing of spark's to safe engine from detonation. As cold air creates less prerequisites for detonation.
Look abaout this articile for more performance.

pp Please read more carefully about methanol. It is very toxic fuel.
