APR Drop In Intake Filter (4M/9Y/SUV) - 2.9T/3.0T/4.0T | RF100022

The APR Drop-In Intake Filter (RF100022) is a high-performance replacement for the restrictive factory paper filters found in the 2.9T, 3.0T, and 4.0T engines used across the Audi, Porsche, Bentley, and Lamborghini SUV lineups. Engineered on a flow bench to optimize internal geometry beyond just changing the media, this filter provides up to 12% more airflow than the stock unit. By reducing the pressure drop, it allows the turbochargers to reach target boost with less effort, resulting in improved efficiency and sharpened throttle response.

Constructed from premium, multi-layer cotton gauze, the RF100022 provides excellent filtration while being fully washable and reusable. This makes it a lifetime upgrade that pays for itself over time. It is an ideal "Stage 0" modification for owners looking to improve engine breathing and add a subtle, sophisticated increase in induction sound without replacing the entire airbox assembly.

Features:

• Increased Efficiency: Flows up to 12% more than the stock paper filter, maximizing performance potential.
• Reduced Turbo Strain: Lower pressure drop at the compressor inlet improves turbocharger longevity and spool-up time.
• Sustainable Design: Washable and reusable cotton gauze media eliminates the need for future filter purchases.
• Flow-Bench Optimized: Every design revision was verified on a flow bench to ensure real-world CFM gains.
• Enhanced Induction Sound: Provides a subtle, refined increase in engine and turbocharger acoustics.
• Emissions Friendly: 100% direct-fit replacement that maintains full emissions compliance and factory airbox integrity.
