IE Carbon Fiber Intake System – Audi B9/B9.5 RS5 & RS4

IE's Carbon Fiber Intake System for Audi B9/B9.5 RS5 and RS4 models is engineered with uncompromising precision. The one-piece carbon fiber airbox increases volume and airflow while managing intake air temperature (IAT), improving turbo and engine efficiency. Enjoy a noticeable power increase and seamlessly combine style, sound, and performance in your RS-class Audi.

KEY FEATURES

  • High-gloss genuine carbon fiber construction

  • Sealed, seamless 1-piece airbox – no leaks

  • Up to +28 hp & +26 Nm over stock (with IE Turbo Inlet)

  • Up to +39.27% more flow than stock

  • Complete your intake with IE Turbo Inlet pipe (optional)

  • Improved turbo and engine sound

  • High and low pressure feed for all power levels

  • Massive 5” filter & velocity stack ensure laminar airflow

  • Factory-style mounts for easy and secure installation

PERFORMANCE ENGINEERING – TANGIBLE POWER

IE engineers have designed every millimeter to minimize turbulence and maximize internal volume. All restrictions have been removed: more airflow, larger filter surface area, and heat protection to keep IAT low. The result: the full potential of engine software and hardware is unleashed.

OPTIONAL TURBO INLET – COMPLETE YOUR INTAKE

The IE Turbo Inlet upgrade removes the last remaining restrictions, providing a complete, high-flow system from filter to turbo. Made from aerospace-grade aluminum, the massive 3.2” inner diameter delivers up to +39.27% more flow than the stock pipe and finishes off the engine bay with a sleek look. (Sold separately.)


ONE-PIECE AIRBOX – STYLE & RELIABILITY

The seamless 1-piece construction ensures style and worry-free use. Unlike multi-piece solutions from competitors, this eliminates air leaks, difficult installation, extra noise, and parts loosening over time. It also ensures the smoothest possible airflow.

UNIQUE SOUND – ENJOY ALL REVS

Sound is as important to the driving experience as power. Enjoy the addictive twin-turbo spool, throttle response, and blow-off valve sounds – which the factory airbox muffles. This system makes the sounds clear and sporty, perfectly complementing the improved performance.


VELOCITY STACK – UNINTERRUPTED POWER

A rare solution in consumer-grade products: the integrated velocity stack guides airflow from the 5” filter to the turbo inlet as efficiently as possible. It reduces resistance and turbulence and maximizes engine and turbo air demand thanks to a controlled, funnel-shaped transition.

DUAL AIR ZONES – AIR FOR ALL POWER LEVELS

The carbon fiber airbox utilizes multiple intake channels to support various tuning stages. The wide front opening acts as a ram air solution for high-pressure air, and additional filter intake openings draw air from the engine bay's low-pressure area. This ensures the entire filter receives unobstructed airflow – without power limitations, even in extreme tuning setups.


TECHNOLOGY-REFINED – QUALITY IN THE DETAILS

The IE team uses state-of-the-art 3D scanners and software to measure the engine bay, bumper, grille, and hood. The precise digital model allows every millimeter to be utilized, resulting in a perfectly fitting, stylish, and high-quality construction.
