APR Carbon Intake System CI100043 for Audi B9 S4 | S5 3.0T (2018-2025)

The APR Carbon Intake System CI100043 is engineered specifically for the Audi B9 S4 and S5 models equipped with the 3.0T engine from 2018 to 2025. This complete intake upgrade addresses the limitations of the factory system, providing significant performance benefits through enhanced airflow and reduced restrictions.

Performance Gains

With the APR system, expect an impressive increase of +19 AWHP and +20 AWFT-LBS of torque when paired with the APR Stage 1 (93) tune. This intake flows 31% more air than the stock setup, effectively reducing pressure drop and improving turbocharger efficiency, allowing your engine to perform at its best.

Comprehensive Design

The APR CI100043 replaces all intake components from the inlet scoop to the turbo inlets, ensuring that all potential restrictions are addressed. The factory turbocharger inlet pipe is a known bottleneck due to its limited size. The APR system features a large 4-inch filter outlet that maintains a consistent diameter all the way to the turbo inlets, optimizing airflow and minimizing pressure loss.

Material and Construction

Crafted from high-quality carbon fiber, this intake system not only looks impressive but also maximizes performance. The lightweight nature of carbon fiber allows for thinner walls, which increases internal diameter and enhances airflow. Its design incorporates complex shapes to fit snugly within the engine bay, ensuring a seamless installation.

Filter Specifications

The intake system includes a substantial 7" x 7" filter with a 4" outlet and a 5.5" frontal inlet. This high-flow, washable pleated cotton gauze filter offers excellent filtration while maintaining airflow efficiency. Its large surface area ensures that it remains effective for extended periods, reducing the frequency of replacements.

Installation and Compatibility

The APR Carbon Intake System comes with all necessary components for a straightforward installation, including new OEM gaskets, bolts, and clamps. There is no need for additional tuning, and the system is designed to be emissions friendly. The inclusion of billet turbo inlet adapters allows for future upgrades to larger turbochargers without needing to replace the entire intake system.
