This item also fits additional vehicles. See Tech Specs below.
Proper maintenance is key to obtaining the best fuel mileage from your TDi. The Mishimoto Audi A6 TDi Racing Thermostat is an ideal upgrade for improved cooling efficiency and protection against the dangers of high coolant temperatures. Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures. Once the engine is fully warmed up, the Mishimoto low-temperature racing thermostat will open at a lower temperature (71°C) compared to standard thermostats (87°C). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Mishimoto Audi thermostats are digitally calibrated, utilize high-quality wax to ensure precise and consistent opening temperatures, and include a gasket for seamless, leak-free installation. Trust the Mishimoto thermostat to maintain optimal coolant temperatures in your TDi. As with all our products, this racing thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
