Mishimoto racing thermostat for the 2017+ Honda Civic Type R (FK8/FL5, K20C1 turbo). It begins opening at 68°C / 154°F — 10°C earlier than stock — and is fully open 7°C earlier at 83°C / 181°F, letting coolant flow into the radiator and shed heat sooner. Direct-fit replacement, backed by the Mishimoto Lifetime Warranty.
