Mishimoto 2015+ VW Golf-R MK7/2013+ Audi 8V S3 Performance Auxiliary DSG Cooler/Heat Exchanger

If you've got a 2014-2021 Audi TT Quattro, especially one that's seen some performance upgrades, you know how quickly heat can build up. The MQB platform engines in these cars can make impressive power, but that extra power means more heat for the engine, transmission fluid, and oil. Even with the stock auxiliary coolers, you might notice performance drops or worry about temps after hard driving. Mishimoto has developed a performance auxiliary heat exchanger to help keep things cool.

This Mishimoto cooler is designed to replace your stock auxiliary heat exchanger or DSG cooler, or even work alongside them. It significantly increases the core volume by 52-percent and coolant capacity by a substantial 106-percent over the factory unit. The core uses louvered fins to improve airflow and increase surface area, while a dual-pass design balances cooling efficiency. Strutted tubes add durability, and it even comes with a stainless-steel stone guard to protect against road debris. This means you can push your car harder for longer without worrying about overheating.
