The factory airbox restricts maximum airflow to keep induction noise down and meet strict regulations. Upgrading your induction hardware allows the 2.0T B48 engine to breathe freely, dramatically improving turbo spool, sharpening throttle response, and amplifying the addictive turbo intake roar. Ditch the restrictive factory setup with high-volume Induction kits to maximise your cold air feed, or choose drop-in high-flow panel filters for a highly effective, stealthy OEM+ upgrade. Eliminate narrow factory bottlenecks by installing smooth silicone induction pipes & hoses for unrestricted, high-velocity airflow directly into the turbocharger.
