VCTR Performance Audi S4/S5 B9 Intake System

Overview

The factory intake on the B9 S4 and S5 was designed with noise suppression as a priority — not airflow. As the EA839 3.0T is pushed harder or remapped, the restricted OEM inlet path becomes a limiting factor. This intake system replaces it with a more direct route to the turbos, sharpening induction sound and supporting improved airflow delivery.

Why Upgrade?

• Improved airflow path to the turbochargers compared to the factory intake
• Sharper induction sound and more turbo character through the rev range
• Cleaner, more purposeful engine bay presentation
• Direct OEM replacement — no permanent modification required

Engineering Focus

Constructed from 6061 aluminium, the pipework is sized for both stock and tuned EA839 applications. The intake replaces the factory airbox and inlet assembly with a more open design, improving how the turbos draw air at higher demand.
