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
