    Introducing the APR Full Intake System for the Audi S4 and S5 (B9) 3.0T EA839

    Product Page

    APR 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 when paired with the APR Stage 1 (93) tune.



    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.

    Testing Results That Speak for Themselves



    The performance of the factory intake system is no match for the APR Full Intake System. The stock setup is limited to a maximum flow of 400 CFM at 28” H2O, whereas our full intake system achieves a significant 31% improvement, flowing 525 CFM under the same conditions.

    This increase in airflow is paired with a dramatic reduction in pressure drop across the system, allowing the turbocharger to spool faster and operate in a more efficient range of its compressor map. The result is not just theoretical—it’s power you can feel.

    On our Stage 1 (93) tuned Audi S4, simply installing the APR Full Intake System delivered an additional +19 AWHP and +20 AWFT-LBS of torque, proving its capability to unlock your vehicle’s full potential.

    Arin,

    Can you go into how this version is different than the previous intake and how is it been tested to assure it doesn't have the same issues as the previous iteration?

    The previous system had a PEX turbo inlet. We've changed it to a higher temp composite material. This system has been on our development cars for around a year or so.

    Will there be available an optional integral turbo inlet/intake pipe that is sized for and will directly bolt up to the APR stage 3 turbo?

    Yes, its fits! The pipe comes with the proper adapter for the factory turbo, and the turbo comes with a larger that bolts right up.
