For more information, visit www.P65warnings.ca.gov.The APR Full Intake System (CI100067) is the ultimate induction solution for the Audi B9/B9.5 RS4 and RS5 2.9T. Unlike partial upgrades that are forced to neck down to factory diameters for compatibility, this comprehensive system replaces every component from the frontal air scoop to the turbocharger inlets. By utilizing thin-walled, heat-resistant composite materials, APR has maximized the internal diameter within the cramped RS5 engine bay, resulting in a 36% increase in airflow and significant power gains of +19 AWHP and +17 AWFT-LBS on Stage 1 tuned vehicles.
The system features a high-performance PEX airbox designed to shield the intake tract from engine bay heat while incorporating strategic cutouts in low-temperature zones to optimize airflow and sound. At the heart of the system is a massive 7” x 7” washable cotton gauze filter, providing a vast filtration surface area that reduces pressure drop and allows the twin turbochargers to spool faster. This "future-proof" design also includes a removable billet turbo inlet adapter, making it compatible with larger aftermarket turbochargers down the road.
Key Features:
- Full System Overhaul: Replaces the inlet scoop, airbox, massive filter, and turbo inlet pipes to eliminate all factory bottlenecks.
- Proven Power: Verified gains of +19 AWHP and +17 AWFT-LBS over stock intake (tested on APR Stage 1 93 octane).
- Massive Flow Gains: Increases airflow from 484 CFM (stock) to 658 CFM—a 36% improvement.
- Enhanced Turbo Response: Dramatically reduces pressure drop, allowing turbos to spool faster and work more efficiently.
- High-Tech PEX Construction: Heat-resistant composite material allows for thinner walls and larger internal diameters than traditional plastic or metal.
- 7” x 7” Washable Filter: Large pleated cotton gauze media with a 5.5” frontal inlet for maximum air volume and filtration.
- Future-Proof: Removable billet turbo inlet adapters can be swapped to accommodate larger turbocharger setups.
- Refined Sound: Provides a sporty, sophisticated engine note that highlights the 2.9T twin-turbo soundtrack.
