The APR 4.0T EA825 Intake System is here for the Audi (C8) RS6 and RS7! The APR Intake System is a substantial upgrade for the 4.0T EA825 engine. It offers significant horsepower and torque gains through a high flow design that greatly increases airflow while reducing pressure drop.
We've upgraded every part that actually translates to increased performance. Throttle response sharpens, as the system lets your engine to breath more freely. This causes the turbochargers to work less hard, which directly translates to the gains you feel. On top of that, the stunning carbon fiber and aluminum design looks fantastic in the engine bay and adds a pleasant auditory note to the engine.
The filter is washable and reusable, and the cast aluminum turbo inlets use adapter rings with ideal entrances, making them compatible with larger turbochargers. This lets the system support even higher airflow levels, with low pressure drop, and even more horsepower and torque as you continue to mod!

Design Overview and Testing: There was no component overlooked in the search for performance; the airbox, filter, couplers, and turbo inlets were each extensively analyzed and modified for maximum flow.
The upgraded APR filter unit, featuring a low restriction cotton gauze media, flows 8% more than stock without sacrificing air quality. Flow is further improved by 52% larger airbox outlets, and 93% larger turbo inlets. The significantly improved APR turbo inlets are compatible with turbos featuring up to a 29% larger inlet port; various inlet adapters ensure that the APR intake will provide optimized flow for a wide range of turbos.

Overall flow improvements of the intake result in a 50% reduction in pressure drop compared to OEM. The APR intake flows 19% less than the theoretical maximum supported by the OEM turbo inlet port diameter; a significant improvement compared to the OEM intake which flows 37% less than the theoretical maximum. Such significant improvements in flow quality and quantity are manifested in faster throttle response, reduced strain on the turbo, and increased efficiency which translates to more power. On the Stage 1 (93) APR RS6, an additional 47 AWHP and 38 AWFT-LBS of torque, to all four wheels, was measured on our calibrated chassis dynos. Whether you are looking to improve the performance of your stock RS6, or pushing the limits with larger turbos, the APR intake will support your efforts.
