Wagner Tuning Performance Intercooler + Catted Downpipe Package Audi RS4 Avant (B5)

Wagner Tuning Performance Intercooler + Catted Downpipe Package - Audi RS4 Avant (B5)

Wagner Tuning brings serious airflow and turbo efficiency to the Audi RS4 Avant with this Competition Package, pairing their Performance Intercooler Upgrade Kit with a catted Downpipe Kit. Engineered with CAD/FEM optimised cast aluminium end tanks and the latest tube fin core technology, the combo is built to remove factory bottlenecks and support increased charge cooling and airflow.

This listing covers the Audi RS4 Avant (B5) and includes both the Intercooler Upgrade Kit (SKU 200001139) and the Downpipe Kit (SKU 500001001), supplied together under package SKU 700001002.

Note: The downpipe uses the RS4/RS6 turbo double flange. Fitting to an Audi S4 (B5) requires linkpipes to be fabricated and rear lambda cables extended if fitted — this is outside the standard RS4 fitment covered here.
