The Audi RS5 and RS4 B8 Eventuri intake was developed to give less restrictive airflow to the engine whilst maintaining low inlet temperatures. The 4.2 V8 engine bay becomes heat soaked very quickly so simply having an open cone system would result in better airflow but higher inlet temperatures. Eventuri therefore completely re-engineered the inlet system from the throttle bodies to the front grill with a highly efficient carbon fiber sealed system able to produce a huge extra 23hp.
