The factory airbox restricts maximum airflow to keep induction noise down. Upgrading your induction hardware allows the twin-turbo V6 engine to breathe freely, dramatically improving turbo spool, sharpening throttle response, and amplifying the intake roar.

Induction Kits & Panel Filters: Ditch the restrictive factory setup with high-volume induction kits to maximise cold air feed, or choose drop-in high-flow panel filters for a highly effective OEM+ upgrade.

Future Additions: As the range of intake/induction parts expand for the RS4/RS5 B9, expect to see enlarged turbo elbows and smooth silicone induction pipes & hoses for unrestricted airflow directly into the turbos.
