Fits select 2009-2017 Audi A6, A7, A8, Q5, Q7, S4, S5, SQ5, and Volkswagen Touareg models.

The Mishimoto MMTS-S4-10 Racing Thermostat is engineered to improve cooling efficiency by promoting earlier coolant circulation. Designed as a direct-fit upgrade, this thermostat begins opening at 159.8°F (71°C), which is 25.2°F (14°C) earlier than the factory unit. By allowing coolant to flow into the radiator sooner, it helps manage thermal loads more effectively during high-performance driving or in demanding climates.

This kit includes an OEM-quality thermostat housing to ensure a precise, leak-free seal and simplified installation. Whether you are addressing a common cooling system failure or preparing a vehicle for track use, this lower-temperature thermostat provides a reliable solution for engine temperature management.
