APR 18-25 Audi S4/S5/S5 Sportback (B9) 3.0T PEX Intake System

Introducing the APR Full Intake System for the Audi S4 and S5 (B9) 3.0T EA839APR is proud to unveil the Full Intake System for the Audi S4 and S5 (B9) 3.0T 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 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 +20 AWFT-LBS of torque on our APR Stage 1 (93) equipped S4.Additionally, the APR Full Intake System is engineered with functionality, performance, and sound in mind.
