Introducing the APR Full Intake System for the Audi RS4 and RS5 (B9) 2.9T EA839

APR is proud to unveil the Full Intake System for the Audi RS4 and RS5 (B9) 2.9T EA839—an all-in-one solution designed to deliver maximum airflow, enhanced turbocharger efficiency, and real, measurable performance gains.


The APR Full Intake System is perfect for Audi enthusiasts seeking the ultimate intake upgrade. Unlike others that address only a portion of the intake system, requiring the inlets and outlets to neck down to the factory diameter for compatibility, this comprehensive solution replaces every component from the inlet scoop to the turbocharger inlet. This eliminates restrictions throughout the system, ensuring unmatched airflow and turbo performance with the largest inlet physically possible.


Key to the system’s superior performance is its optimized design. Making the inlet as large as possible is the goal but space is extremely limited. By maximizing the internal diameter with thin-walled heatresistant composite materials, APR achieves an impressive 31% more airflow compared to stock. This translates directly into improved turbocharger efficiency, faster spool times, and significant power gains, adding +19 AWHP and +17 AWFT-LBS of torque on our APR Stage 1 (93) equipped RS5. Additionally, the APR Full Intake System is engineered with functionality, performance, and sound in mind. The PEX airbox shields the filter from the engine bay, while its thoughtfully placed cutouts provide additional airflow and a refined engine sound. A massive 7” x 7” washable pleated cotton gauze filter further enhances performance with vast filtration surface area while ensuring long-lasting usability.


Whether you’re focused on unlocking power, enhancing turbo performance, or future-proofing your vehicle for upgrades, the APR Full Intake System is the only intake you’ll ever need.
