For more information, visit www.P65warnings.ca.gov.The APR High-Flow Intake Filter (RF100028) is a premium "drop-in" performance upgrade specifically designed for Audi B8 and B8.5 chassis vehicles. By replacing the standard, restrictive paper filter with APR’s proprietary washable cotton-gauze media, you can significantly reduce air intake restriction. This allows the 2.0T engine and turbocharger to breathe more freely, resulting in improved throttle response, decreased turbo lag, and more consistent power delivery across the entire powerband.
Flow-bench optimized and backed by decades of intake engineering, this filter balances high-volume airflow with superior filtration to protect your engine for hundreds of thousands of miles. Because the media is washable and reusable, it represents a permanent solution that eliminates the need for future paper filter replacements. It is the ideal "stealth" upgrade for owners who want to maximize the performance of their factory airbox while maintaining an OEM engine bay aesthetic.
Key Features:
- High-Flow Performance: Flows significantly more air than factory paper filters, reducing the work required by the turbocharger.
- Proprietary Filtration: Multi-layer cotton-gauze material provides excellent protection against dust and debris.
- Washable & Reusable: Environmentally friendly and cost-effective; designed to last the entire life of the vehicle.
- Improved Response: Noticeable reduction in turbo lag and sharper throttle response during spirited driving.
- B8 Platform Specific: Precision-sized at 323mm x 128mm for a perfect, airtight seal within the factory airbox.
- Enhanced Sound: Provides a subtle increase in engine induction and turbocharger spool sound.
- Emissions Compliant: Does not negatively impact vehicle emissions or trigger fault codes.
