APR 18-25 Audi S4/S5/S5 Sportback (B9) 3.0T Carbon Fiber Intake System

This is the ultimate intake upgrade for the Audi S4 and S5 (B9). It flows 31% more than stock, reduces pressure drop, and improves turbocharger efficiency. This directly translates to +19 AWHP and +20 AWFT-LBS of torque on top of our Stage 1 (93) tune making this a simple upgrade for more power you can feel.Our system is a full upgrade as it replaces all of the intake components from the inlet scoop all the way to the turbo inlet. This is extremely important as focusing on the airbox alone does not address the main restrictions found in the factory intake system. Simply put, our system flows better than stock, makes more power, puts less strain on the turbocharger, looks sexy under the hood with the gorgeous carbon fiber design, and enhances the sound of the engine.The factory turbocharger inlet pipe is a big restriction point because it's small. It's common for most intake systems to only focus on the filter and airbox, but doing so only has minimal impact on performance. Furthermore, upgrading the turbocharger inlet pipe only has minimal impact on performance if it still necks down to with the factory or aftermarket intake airbox. We solve this by making our pipe as large as possible from the 4" filter outlet all the way to the turbocharger inlet in one piece! This minimizes pressure drop and increases flow through the system far better than a multi-piece solutions.Our system is made from carbon fiber and looks absolutely stunning under the hood. By using this material we are able to make the wall-thickness of the tubes smaller, maximizing the internal diameter, increasing performance even more! The material also allows us to make complex organic shapes necessary when working in a tight engine bay. Fits 2018-2024 Audi S4/S5/S5 Sportback

Upgrade your Audi S4 and S5 (B9) with the APR Carbon Fiber Intake System, designed to significantly enhance airflow and engine performance. This full intake system replaces all factory components from the inlet scoop to the turbo inlet, addressing critical restrictions that limit power and efficiency. The system's innovative design flows 31% more air than stock, reducing pressure drops and enabling your turbocharger to operate more efficiently, which results in an impressive +19 AWHP and +20 AWFT-LBS of torque when paired with our Stage 1 (93) tune. The comprehensive upgrade not only delivers measurable power gains but also improves throttle response and turbo spool times, providing a more responsive driving experience.

Constructed from lightweight, high-quality carbon fiber, the APR intake looks stunning under the hood while offering functional benefits. The material allows for complex organic shapes and thinner walls, maximizing internal diameter and internal airflow. The design features a massive 7” x 7” filter with a 4” outlet, ensuring high flow capacity and easy maintenance with washable pleated cotton gauze filter material. Unlike competing systems that only upgrade the airbox or focus on the filter alone, this system addresses the entire intake pathway, including a large diameter inlet pipe from the filter to the turbocharger, which minimizes pressure restrictions and optimizes airflow. A billet turbo adapter ring is included to facilitate larger turbo setups if needed, making this system versatile for various performance applications.

This intake system also incorporates additional flow paths within the airbox, directing airflow away from the engine to further enhance efficiency. It is emissions friendly and includes new OEM gaskets for a perfect fit. The system not only boosts performance but also enhances the engine sound, giving your vehicle a more aggressive tone. Easy to install, the APR Carbon Fiber Intake System is a comprehensive upgrade that combines form, function, and style, making it a top choice for enthusiasts seeking maximum performance and a refined under-the-hood look.
