Audi 4.0T V2 Intercooler/Charge Cooler Core
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Previous ESTIMATED time of arrival around SEPTEMBER 22nd is no longer valid.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.
Out of stock
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.

Pierburg CWA150 Pump – with Audi harnessAvailable on: October 10, 2023 at 12:14 pm
NOTE: Please update your pump fuse to 25 amps
The CWA150 is basically the high-pressure variant of the CWA100-3 we are also offering.
The dimensions and the weight are nearly the same.
The new pumps have a new designed impeller and impeller housing to accommodate for the higher differential pressures.
It is suitable on anything that profits from that higher pressure capability to maintain consistent flow when added volume and larger heat exchangers are used.
