Audi S4 / S5 B9 2.9 TFSI Eventuri Carbon Fiber Intake System

The Audi S4/ S5 B9 2.9 TFSI Eventuri intake was developed to give less restrictive airflow to the turbo whilst maintaining low inlet temperatures. The 2.9T 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 intake pipe to the front grill with a highly efficient carbon fiber sealed system able to produce a huge extra 17hp on stage 1 !
