Mishimoto racing thermostat for the 2002-2006 Acura RSX (and 2003-2005 Honda Civic / CR-V), opening at 60°C — lower than the stock 78°C — so coolant flows through the engine sooner to reduce and maintain cooler temperatures, ideal for modified and turbocharged builds. Direct-fit replacement, backed by the Mishimoto Lifetime Warranty.
