Intake System | B9/B9.5 SQ5 | Integrated Engineering

Overview

Increase airflow, sharpen throttle response, and unleash the unmistakable sound of your turbocharged EA839 engine with the Integrated Engineering Performance Air Intake System for the Audi B9/B9.5 SQ5 3.0T. Designed using a one-piece rotomolded polymer airbox and a massive 5-inch high-flow air filter, this intake delivers up to 19 horsepower and 21 lb-ft of torque on tuned vehicles while maintaining low intake air temperatures and factory-like fitment.

Engineered to outperform the restrictive factory airbox, the IE Intake System flows up to 24% more air on its own and up to 50.4% more airflow when paired with the optional IE Turbo Inlet. Whether your SQ5 is stock, tuned, or equipped with a hybrid turbocharger, this intake provides the airflow capacity, sound, and efficiency needed to support your build.

Design Highlights

Rotomolded Polymer Construction

The intake housing is manufactured using a rotational molding process that creates consistent wall thickness, superior strength, and exceptional heat resistance. This manufacturing method also allows complex internal shapes that maximize intake volume while promoting smooth airflow for improved performance.

Seamless One-Piece Design

Unlike multi-piece intake systems, the IE intake utilizes a single-piece airbox for an OEM-quality appearance, exceptional durability, and factory-like fitment. The clean design minimizes potential leak points while providing a premium engine bay appearance.

Integrated Velocity Stack

A built-in velocity stack creates a smooth transition between the oversized air filter and the turbo inlet, reducing turbulence while increasing airflow efficiency. The result is improved laminar airflow, lower restriction, and greater turbocharger efficiency.

Optional Turbo Inlet Upgrade

The intake system is designed to integrate seamlessly with the optional IE Turbo Inlet Pipe. Together, the combination increases airflow from 24% over stock to an impressive 50.4%, further reducing restrictions between the airbox and turbocharger.

Note: The IE Turbo Inlet is sold separately and can be installed during the initial intake installation or added at a later date.

Hybrid Turbo Ready

The intake and optional turbo inlet are engineered to support stock and many aftermarket hybrid turbochargers. Optional CNC-machined adapter rings allow the system to maintain maximum airflow while adapting to larger compressor inlets without introducing restrictions.

Note: Hybrid turbo adapter rings are sold separately from the IE Turbo Inlet.

Dual Pressure Airflow Design

The intake utilizes multiple airflow paths to ensure unrestricted air supply at every power level. High-pressure ram air enters directly from the front grille, while additional airflow is supplied through strategically positioned low-pressure filter plate louvers whenever engine demand increases. This dual-zone approach helps maintain consistent airflow even on high horsepower applications.

Enhanced Performance Sound

The factory airbox is designed primarily to suppress engine and turbocharger noise. The IE Intake System allows the sounds of turbo spool, throttle response, and diverter valve operation to be heard clearly while maintaining excellent filtration and drivability.

Precision Engineered

Using advanced 3D scanning technology, Integrated Engineering engineers optimized every available millimeter of engine bay space to maximize airflow while ensuring hassle-free installation, OEM-quality fitment, and long-term reliability.

Notes

• Power gains are achieved on properly tuned vehicles.
• Maximum airflow is achieved when paired with the optional IE Turbo Inlet.
• Hybrid turbo applications require the optional IE Turbo Inlet and the appropriate adapter ring.
• No permanent vehicle modifications are required for installation.
