Mishimoto MM Thermostats - MMTS-F80-15

The Mishimoto racing thermostat for the BMW M3/M4 2015+ F8X and G8X 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 9F (5C) earlier than the stock thermostat at 212F (100C). 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+ F8X and G8X thermostat is backed by our Mishimoto Lifetime Warranty.

Engine coolant thermostat designed to regulate coolant flow and maintain optimal operating temperature. Ensures efficient warm-up, prevents overheating, and supports reliable performance with a precise fit.
