APR Adapter Ring - Audi RS3 (8V) / TT RS (8S) - TTE777/GTX38582R
APR builds its turbocharger hardware around real world fitment accuracy, and this adapter ring is a good example. It's designed to create a port matched transition between the factory intake and the turbocharger inlet, keeping airflow clean and efficient on the Audi RS3 and TT RS platforms running APR's TTE777 or Garrett GTX38582R turbo upgrades.
This listing covers the Audi RS3 (8V) and Audi TT RS (8S) fitted with the APR TTE777 or GTX38582R turbocharger. The ring interlocks with the factory housing to form a seamless entrance, and larger diameter rings are sold separately for those stepping up to bigger hybrid turbo builds.
Note: This adapter ring is specific to the TTE777/GTX38582R turbo fitment. Confirm your turbo specification before ordering, as larger hybrid turbos require a different ring size sold separately.

- Port matched design for a clean transition into the turbocharger inlet
