(1 customer review)


UNFORTUNATELY THE WAGNER TUNING shipment of these cores is now scheduled to arrive the first week of Nov.

Previous ESTIMATED time of arrival around SEPTEMBER 22nd is no longer valid.

NEW!: For 2023 the core has been revamped to add additional density, additional channels, and improved performance. We have also added a bleed port to aid in purging the air out of the system during the initial fill-up.

A true high-performance replacement core for 4.0T Audi Vehicles.  Increases reliability over the OEM core.

The MercRacing intercooler/charge core offers the following benefits:

  • Improved core durability (much stronger than OEM core) OEM core prone to failure when increasing boost.
  • The higher water flow rate with its large full-size 3/4″ hose connections improves core efficiency.
  • Faster IAT recovery during pulls and performance-driving
  • Better airflow (CFM) than OEM core.  The Original core is very restrictive and meant to run at a limited stock flow rate.
  • The new core design in 2023 adds additional Fin density and added cooling columns for improved efficiency.
  • Includes a bleed port to aid in the removal of air during system fill-up.

    This surpassed my expectations on build and quality. This V2 design is way better than V1 and the welds are on point. Packaging was very secure and no issues.
