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.
Fits: BMW M3 (G80), BMW M4 (G82/G83), BMW M2 (F87), BMW M4 (F82/F83), BMW M3 (F80), BMW M5 (F90). Confirm fitment with us before ordering.
