For more information, visit www.P65warnings.ca.gov.The APR Carbon Fiber Intake System (CI100021) is a premium, high-performance hardware upgrade for the Audi B8 A4 and A5 4-cylinder engines. This system is meticulously engineered to increase power by allowing the engine to breathe more freely, optimizing mass airflow while providing superior filtration. By creating a direct, high-velocity airflow path, the APR system replaces the restrictive factory airbox and the problematic rubber inlet snorkel—a component known to collapse under high load and stifle power delivery.
Utilizing a closed carbon fiber design, this intake captures air from the high-pressure zone at the leading edge of the hood for true ram-air induction. Beyond the aesthetic transformation of your engine bay, you can expect sharper throttle response, an enhanced engine note, and lower intake air temperatures (IAT). This system is a "no-compromise" upgrade that functions perfectly with factory tuning, as it does not alter MAF signals or require additional software to operate.
Features:
- Increased Performance: Delivers measurable gains in horsepower and torque by reducing induction restriction.
- Ram Air Design: Maintains the OEM inlet location to utilize the highest pressure area of the vehicle for maximum air ingestion.
- Carbon Fiber Construction: A beautiful, closed-element system that shields incoming air from engine bay heat and prevents heat soak.
- Eliminates Snorkel Collapse: Replaces the factory rubber inlet with a rigid structure to ensure consistent power delivery under heavy load.
- High-Flow Filtration: Includes a pleated cotton gauze filter that is both highly efficient and washable/reusable.
- OEM+ Integration: Does not require ECU software and is designed not to interfere with factory MAF sensor readings.
- Enhanced Sound: Provides a more aggressive, audible intake growl without being overly intrusive.
Product Contains:
- (1) Carbon Fiber Airbox Assembly
- (1) High-Flow Pleated Cotton Gauze Filter
- (1) Set of Specialized Mounting Hardware and Couplers
Important Fitment Note: While this is a direct bolt-on for the A4 and A5, facelifted Q5 models may require minor undertray trimming for perfect clearance. This system is designed for 4-cylinder longitudinal engines only.
Warranty: This product is supported by a Manufacturer's Warranty. Note: Manufacturer warranty terms are subject to change.
