The Mishimoto racing thermostat for BMW M3/M4 (2015+ F8X and G8X) begins opening 9°F (5°C) earlier than the stock unit, allowing coolant to enter the radiator sooner at approximately 212°F (100°C). It includes a cast aluminum housing for OEM-style fit and is offered as a direct-fit component to support more efficient cooling when used with performance radiators, backed by Mishimoto's Lifetime Warranty.
