APR 19-24 Audi RS5/RS5 Sportback (B9) 2.9T PEX Intake System

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 heat-resistant 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. Fits Audi RS5 18-25
