The Audi B8 S4 3.0TFSI
carbon intake system from Eventuri
was developed to give less restrictive airflow to the supercharger whilst maintaining low inlet temperatures. The S4 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but higher inlet temperatures.
They therefore completely re-engineered the inlet track from the throttle body to the front grill with a highly efficient sealed system. The restrictive stock airboxes and duct feeds have been replaced with a Venturi filter housing and a duct system with smooth transitions to allow the airflow to remain full and laminar. The resulting performance gains and aesthetics are industry leading for this platform.
With a stunning carbon weave and fenomenal design quality; this truly is a new benchmark. The B8 S4 Eventuri system uses their Patent Pending Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.
Having an effective cold air feed to the filters is an essential part of the design. Simply having some heat shields in place is not an effective means of avoiding heated air from entering the filters unless the shields create an air tight envelope around the filters. The scoops and ducts in our system combine to provide the filter openings with ambient air and maintain low intake air temperature.
This intake system is available in black carbon fibre as well as a range of Kevlar options in Red, Blue, Yellow or Orange. Performance Gain: 17-22hp, 30-34ft-lb
