EVENTURI EVE-B9S5-CF-INT Intake System (Carbon Fiber) for AUDI B9 S5 / S4

Description EVENTURI EVE-B9S5-CF-INT Intake System (Carbon Fiber) for AUDI B9 S5 / S4

The EVENTURI EVE-B9S5-CF-INT carbon fiber intake system is engineered specifically for the Audi B9 S4 and S5 to deliver measurable improvements in performance and efficiency. Featuring a fully sealed Venturi-based intake design, this system replaces the restrictive factory airbox and plastic inlet pipe with a high-flow carbon fiber housing and precision-formed ductwork. The result is a smoother and more direct airflow path, optimized for maintaining low intake air temperatures while reducing pressure loss to the turbo.

By isolating the intake from engine bay heat and improving volumetric efficiency, the system provides consistent gains in both power and real-world acceleration. V-Box testing confirmed a reduction of 0.5 seconds in 60–130 mph acceleration, demonstrating improved turbo response and airflow dynamics under load. Ideal for performance-focused applications, this intake integrates seamlessly while enhancing both function and aesthetics.
