Treat your British classic to a dose of reliability with the Mishimoto low-temperature thermostat. Proper maintenance of the cooling system is key for optimal performance and essential for extending the life of your engine. A Failed thermostat can lead to overheating, accelerated engine wear, and potential internal engine damage. The Mishimoto Triumph Racing Thermostat is precision engineered to provide your vehicle with years of reliable service and 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 will open at a lower temperature (180F) compared to standard thermostats (195F). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Mishimoto thermostats are digitally calibrated, utilize high-quality wax to ensure precise and consistent opening temperatures, and include a gasket for seamless, leak-free installation. Whether you have a track day GT6 or a wedge TR8 cruiser, trust Mishimoto to keep your Triumph on the road and out of the shop! As with all our products, this racing thermostat is guaranteed by the Mishimoto Lifetime Warranty
