MISHIMOTO VW/Audi MK7 Aluminium DSG Cooler/Heat Exchanger 15+

The VW/Audi MQB platform provides an exceptional foundation for both sleeper street builds and dedicated track applications. Vehicles such as the VW Mk7/Mk8 Golf R, Audi 8V S3, and 8S TT 2.0 TSI deliver impressive power potential from the TSI/TFSI engines, with simple bolt‑on upgrades and tuning capable of adding over 100 horsepower and 120 lb‑ft of torque. Increased output, however, generates significant thermal load across the drivetrain.

MQB vehicles rely heavily on coolant‑based heat management for the engine, transmission fluid, and oil. Even with up to two factory auxiliary heat exchangers, sustained high‑load operation can result in reduced transmission performance and elevated oil temperatures beyond safe limits. To maintain consistent cooling and extend track endurance, Mishimoto offers a high‑capacity solution for the MQB platform.

The Mishimoto 2015+ VW/Audi MQB Performance Auxiliary Heat Exchanger is engineered as a direct upgrade for the stock auxiliary cooler, DSG cooler, or both. Core volume increases by 52 percent, while coolant capacity expands by 106 percent compared to the OEM unit. Louvered fins promote efficient airflow through the core and increase external fin surface area by 68 percent. A dual‑pass flow layout optimizes coolant residence time for improved thermal efficiency, and strutted tubes reinforce the core for durability under demanding road and track conditions.

A stainless‑steel stone guard is included to protect the heat exchanger from debris encountered during spirited driving or track use. As with all Mishimoto VW/Audi performance components, the 2015+ MQB Performance Auxiliary Heat Exchanger is backed by the Mishimoto Lifetime Warranty.
