Mishimoto 06-15 Lexus IS250 Racing Thermostat - 68C

The Mishimoto racing thermostat for the Lexus IS250 2006-2015 is designed to help your cooling system operate at peak efficiency, whether you're cruising to your local car meet or tearing up the track. Our thermostat begins to open 25.2°F (14°C) earlier than the stock thermostat at 154.4°F (68°C). That allows precious coolant to flow into the radiator and start shedding heat sooner. Couple this thermostat with a Mishimoto performance aluminum radiator and you have the recipe for an engine that runs cool no matter the situation. This 2006-2015 Lexus IS250 thermostat includes an OEM-quality housing for a perfect fit and, like all of our thermostats, it's backed by our Mishimoto Lifetime Warranty.
