Mishimoto Racing Thermostat (Honda Civic Si 2006-2009) Mishimoto

The Mishimoto racing thermostat ensures an optimum level of coolant release in modified and upgraded turbo Civic SI engines. The Mishimoto racing thermostat has a faster response to temperature change, allowing it to regulate high engine temperatures better than a standard thermostat.

Standard thermostats will only start to open at a temperature of 78°C, while the Mishimoto Honda Civic SI racing thermostat activates at a lower temperature of 60°C. Activating at this temperature allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Engines using the Mishimoto racing thermostat will experience greater cooling efficiency, increasing overall performance and preservation of engine health over time. Mishimoto guarantees superior performance and quality with an unmatched lifetime warranty on all parts.
