Mishimoto low-temperature racing thermostat for Chevrolet LSX applications opens at a lower temperature (160°F) compared to standard thermostats (186°F) to allow coolant flow sooner and help reduce peak engine temperatures. The thermostat is noted to fit the 1997–2008 Chevrolet Corvette in manufacturer documentation and is intended for enthusiasts seeking improved cooling efficiency for high-output LSX engines; it is covered by Mishimoto's lifetime warranty.
