The Mishimoto racing thermostat for the BMW M3/M4 2015-2019 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 9°F (5°C) earlier than the stock thermostat at 212°F (100°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 thermostat includes an OEM-quality housing and like all of our thermostats, this BMW M3/M4 2015-2019 thermostat is backed by our Mishimoto Lifetime Warranty.
