Description
Unleash the full potential of your Audi B9 RS5 or RS4 with the IE Carbon Fiber Cold Air Intake System – a high-performance upgrade engineered for enthusiasts demanding superior airflow, refined acoustics, and exceptional power gains. Whether you're running a stock setup or a fully tuned build, this carbon intake delivers immediate and measurable results.
Engineered for Maximum Power
Designed by IE’s expert engineering team, this intake system features advanced CFD-optimized geometry and a seamless airbox architecture that increases intake efficiency and reduces air turbulence. When paired with the optional IE Turbo Inlet Pipe, the system delivers up to +28 horsepower and +26 ft-lbs of torque on tuned engines, with 44.2% more airflow over stock. Even without the inlet pipe, expect up to +19 horsepower and +21 ft-lbs of torque.
High-Gloss Carbon Fiber Construction
Crafted from genuine high-gloss carbon fiber, the IE airbox doesn’t just perform—it turns heads. This durable, heat-resistant material helps maintain cooler intake temps while offering a motorsport-inspired aesthetic that upgrades your engine bay’s look to match its performance.
Seamless, Leak-Free Airbox Design
Unlike multi-piece intakes that risk leaks, vibration, or long-term reliability issues, the IE airbox is a single-piece sealed design. This robust construction eliminates unwanted noise, installation complexity, and long-term wear, ensuring consistent airflow and performance under all conditions.
Integrated Velocity Stack for High-Velocity Flow
A massive 5-inch high-flow air filter and built-in velocity stack work in tandem to accelerate airflow and reduce drag as air transitions into the turbo system. This design preserves laminar flow and minimizes turbulence, maximizing both turbocharger response and engine efficiency.
Dual Pressure-Zone Airflow Pathways
The IE airbox is engineered with dual airflow zones: a front-mounted high-pressure ram-air inlet and lower filter plate louvers for supplemental air. These multiple flow channels ensure the filter remains fully saturated with fresh, unrestricted air—even during aggressive driving or on high-power builds.
Immersive Turbo Sound Experience
IE’s intake doesn’t just improve performance—it transforms the sound of your twin-turbo V6. Enjoy the exhilarating audio of turbo spool, sharp throttle inputs, and diverter valve acoustics that were previously muffled by the factory airbox. The result is an addictive soundtrack that complements the raw performance.
Simple, Hassle-Free Installation
This system installs in 20–30 minutes using basic hand tools. With factory-style mounting points and a direct-fit design, installation is quick, secure, and does not require permanent modifications. All required stainless hardware, multi-ply silicone hoses with stop-flat edges, and premium clamps are included for a complete bolt-on experience.
If you’re ready to elevate your RS5 or RS4’s breathing ability, turbo sound, and overall drivability—look no further. The IE Carbon Intake System is your all-in-one solution for superior performance and stunning carbon fiber aesthetics.
