For more information, visit www.P65warnings.ca.gov.The APR Full Intake System (CI100072) is the ultimate induction overhaul for the Audi B9/B9.5 S4 and S5 3.0T. While many intake upgrades on the market only replace the airbox, this comprehensive solution replaces every component from the frontal inlet scoop to the turbocharger inlet itself. By utilizing high-temperature, thin-walled composite materials, APR has maximized the internal diameter in the engine bay's tightest areas, resulting in a 31% increase in airflow and impressive power gains of +19 AWHP and +20 AWFT-LBS on tuned vehicles.
The system features a PEX airbox designed to act as a heat shield against engine bay temperatures while utilizing strategic cutouts to optimize airflow and sound. The heart of the system is a massive 7” x 7” washable cotton gauze filter, providing a vast surface area that reduces pressure drop and allows the turbocharger to spool significantly faster. This system is also "future-proof," featuring a removable billet turbo inlet adapter that can be swapped to accommodate larger aftermarket turbochargers.
Key Features:
- Total Induction Replacement: Eliminates factory bottlenecks by replacing the inlet scoop, airbox, filter, and turbo inlet pipe.
- Verified Power Gains: Delivers +19 AWHP and +20 AWFT-LBS over the stock intake (tested on APR Stage 1 93 Octane).
- Superior Airflow: Flows 525 CFM compared to the stock 400 CFM—a 31% improvement.
- Faster Turbo Spool: Reduced pressure drop allows the turbocharger to reach target boost faster and operate more efficiently.
- Advanced PEX Airbox: High-performance composite construction provides excellent heat deflection with integrated low-temp flow paths.
- Massive 7"x7" Filter: Pleated cotton gauze media is washable, reusable, and provides superior filtration surface area.
- Billet Turbo Adapter: Includes a modular billet adapter that can be changed to support larger turbo upgrades.
- Sporty Sound: Enhances the 3.0T engine note with a refined, sporty tone without being overbearing for daily driving.
