When performance starts with airflow, restrictions aren’t an option. The Untd. Performance Cold Air Intake System for the Audi B9 platform is engineered to deliver increased airflow, sharper throttle response, and an aggressive induction sound—all while maintaining OEM-level fitment and reliability.
Designed for the A4/S4 2.0T, S4/S5 3.0T, and RS4/RS5 2.9T, this intake system replaces the restrictive factory airbox with a high-efficiency, performance-driven solution that allows your turbocharged engine to breathe the way it was meant to.
Key Features:
Increased Airflow & Performance
The high-flow intake design reduces restriction and improves air volume to the turbocharger, resulting in faster spool, improved throttle response, and stronger mid-range power delivery—especially noticeable on tuned vehicles.
Enhanced Induction Sound
Experience a deeper, more aggressive turbo tone under acceleration while maintaining refined drivability during normal cruising. The system enhances turbo spool and diverter valve sounds without excessive cabin drone.
Heat-Optimized Design
Engineered to draw cooler ambient air while minimizing heat soak from the engine bay, helping maintain consistent intake air temperatures during spirited driving.
Direct Bolt-On Installation
Specifically designed for the Audi B9 platform, this intake system installs using factory mounting points and connections. No cutting or modifications required—true plug-and-play performance.
