Eventuri Audi B9 S5/S4 Black Carbon Intake

Vbox road testing on the same stretch of road on the same day cut 60-130mph from 14.72s to 14.24s and 100-200km/h from 12.45s to 12.12s with only the intake added – a larger gain than the dyno suggests, because the intake has the correct flow conditions on the road. The gains come from the sealed system and front air scoop keeping IATs low, the Venturi housing maintaining laminar flow to the turbo with no convoluted rubber section, and the pure pre-preg carbon construction insulating against heat.
