3.0T Polymer Air Intake System

The Integrated Engineering IEINCK5 is a premium polymer air intake system engineered for Audi B9/B9.5 S4 and S5 3.0T models from 2017-2024. Manufactured using a rotomold process, the airbox maximizes internal volume and ensures superior heat resistance with consistent wall thickness and strong corners. Its seamless, single-piece design provides a factory-quality fit and finish. This intake system features a motorsport-designed velocity stack that creates a smooth, low-turbulence transition from the large 5-inch air filter to the turbo inlet, minimizing drag and power-robbing turbulence. The design incorporates high and low-pressure zones, channeling cool ram air from the grille while supplying additional air from under the hood, ensuring airflow demands for various power levels are met. Installation is designed to be straightforward, utilizing factory-style mounts and all stainless hardware, with an estimated install time of 20-45 minutes. However, hybrid turbo adapter rings and the optional cast turbo inlet upgrade are sold separately. The intake system also enhances turbo spool and engine throttle sounds, transforming the driving experience.
