Integrated Engineering B9 S4 CARBON FIBER INTAKE KIT IEINCK3

Unleash the full potential of your Audi B9 S4 3.0T engine with the Integrated Engineering (IE) Carbon Fiber Intake System – a no-compromise upgrade designed for enthusiasts who demand peak performance, stunning design, and refined turbocharged sound. With gains of up to 19 horsepower and 21 ft-lbs of torque, this intake system outflows stock by 37%, and up to 61% on hybrid turbo setups.

Key Features:

• Dyno-Proven Power Gains: Increases up to +19HP and +21 ft-lbs torque on tuned vehicles

• Massive Flow Gains: Flows 37% more than the stock intake on the factory turbo; 61% more with a hybrid turbo setup

• Premium Carbon Fiber Construction: High-gloss, genuine carbon fiber housing provides strength, heat resistance, and visual impact

• 1-Piece Airbox Design: Seamless, leak-proof construction eliminates common multi-piece airbox issues

• Built-In Velocity Stack: Motorsport-style bellmouth design accelerates airflow with minimal drag

• Optional Turbo Inlet Upgrade: Cast aluminum turbo inlet maximizes airflow and supports both stock and hybrid turbos

• Dual Pressure Zones: Ram air effect from grille + low-pressure louvers feed full airflow coverage

• Refined Turbocharged Sound: Enhanced spool, throttle, and diverter valve notes with a clean, powerful tone

• Hybrid Turbo Ready: Modular design supports future turbo upgrades with adapter rings (sold separately)

• Easy DIY Installation: Direct bolt-on fitment using factory mounting points and included stainless hardware

• Precision Fitment: Engineered with 3D scanning for perfect clearance and maximum volume utilization

Performance Testing:

Engineered through extensive flow bench validation, dyno tuning, and real-world driving, the IE Carbon Fiber Intake for the B9 S4 consistently delivers proven results. When paired with the optional turbo inlet, total airflow can reach over 61.43% more CFM than stock – a vital upgrade for tuned and high-output builds.

Optional Cast Turbo Inlet Pipe:

Maximize your intake’s potential with IE’s cast aluminum turbo inlet. It replaces the restrictive OEM plastic unit and maintains the largest possible diameter from intake to turbo. With the inlet installed, total airflow increase can reach up to 61.49%, making it a must-have for serious performance.

Carbon Fiber Done Right:

Beyond its premium appearance, carbon fiber enables complex internal shaping for maximum airflow in tight engine bays. The result is a system that performs as good as it looks, supporting high-boost levels without heat soak or deformation.
