DESCRIPTIONThis item also fits additional vehicles. See Tech Specs below.

A dependable cooling system is a must for your Audi A4, whether it is a daily driver or weekend rallycross competitor. An unreliable and inefficient setup can lead to overheating, accelerated wear, and potential internal engine damage. The Mishimoto Audi A4 2.8L Racing Thermostat is precision engineered to provide your V6-powered Audi with optimal cooling efficiency even in the most demanding environments. 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 opens at a lower temperature (160°F) compared to standard thermostats (189°F). 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 racing thermostat to keep your A4 cool on the highway, back roads, or track. As with all our products, this racing thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
