APR 18-25 Audi RS5/RS5 Sportback (B9) 2.9T Carbon Fiber Intake System

This is the ultimate intake upgrade for the Audi RS4 and RS5 (B9). It flows 36% more than stock, reduces pressure drop, and improves linearization across the turbos. This directly translates to +19 AWHP and +17 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 inlets. 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 turbochargers, 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 inlets 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.The airbox is fed from an inlet scoop that maximizes the flow path into the airbox.

• Inlet piping addresses system restriction, unlike competitive airbox systems that are compatible with factory inlet piping
• Inlet piping diameter is maximized from the 4” filter all the way to the turbochargers
• Billet turbo adapter rings make fitting this system to larger turbos possible
• Massive 7” x 7” filter with a 4” outlet and 5.5” frontal inlet
• +19 AWHP & +17 AWFT-LBS measured over stock (APR Stage 1 93)
• Full intake system: Inlet, airbox, filter, and inlet piping
• High flow and washable pleated cotton gauze filter material
• Airbox has additional flow paths faced away from the engine
• Reduced pressure drop at the turbo inlets
• Improved linearization across the turbos
• Turbos operate more efficiently
• Flows 36% more than stock
• Carbon fiber construction
• New OEM gaskets included
• Enhanced engine sound
