Upgraded heat exchanger for Audi S4, S5, A6, A7, SQ5 3.0TFSI models

Audi 3.0TFSI is a great engine in many ways, unfortunately one of those is creating heat. In this V6 engine the intake temps become an issue in a quite early stage, especially after upgrading the belt pulleys and increasing boost pressure. This heat exchanger has great benefits for even stock engine, but after heavy tuning it’s a must.

Popular amongst Audi enthusiasts, this Merc core offers exceptional heat dissipation with reasonable pricing compared to competitors products.

In case you are in doubt with the compatibility for your car, ask us we are here to help. For maximized efficiency we recommend Amsoil Dominator Coolant from our selection.
