Product Information

Mishimoto performance auxiliary heat exchanger for the VW/Audi MQB platform (2015+ VW Golf R MK7, GTI, and 2014+ Audi 8V S3, TT/TTS), serving as a DSG cooler and auxiliary coolant heat exchanger. It increases core volume by 52 percent and coolant capacity by 106 percent over the stock unit, while louvered fins add 68 percent more fin surface area. A dual-pass design balances flow with cooling, and strutted tubes throughout the core add durability, helping hold safe coolant, engine oil and DSG fluid temperatures on track.
