Mishimoto Racing Thermostat for 1992 Mazda Miata MX5

Eliminating excess heat is something that all performance cars deal with. One way to do this is to use a Mishimoto's Racing Thermostat. They open at a lower temperature to allow coolant flow to start as soon as the engine is warm. This has the effect of removing heat from the cooling system before it starts to build up like it does with the stock thermostat. A cooling running engine has the added benefit of being less likely to suffer from pre-ignition when tuned to the edge.

Most applications open around 154 degrees Fahrenheit. Every thermostat is also covered by Mishimoto's Lifetime Warranty.

Note: Using a racing thermostat may reduce the efficiency of your heating system. This is usually only noticed in very cold climates.
