IE's carbon fiber intake system for your Audi B9/B9.5 RS5 or RS4 has been engineered with meticulous attention to detail. The one-peice carbon fiber airbox increases volume, airflow, and manages intake air temperatures (IATs) to elevate turbo and engine efficiency. Enjoy a boost in power you can feel and seamlessly combine style, sound, and performance for your RS-class Audi.

IE engineers have meticulously crafted every millimeter of this intake system, utilizing intricate shapes and angles to minimize turbulence and maximize internal volume.
