Mishimoto 15-19 BMW M3/M4 Racing Thermostat - 100C

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.This Part Fits: Year Make Model Submodel 2017 BMW 530i Base 2017 BMW 540i Base 2004-2005 BMW 545i Base 2006-2016 BMW 550i Base 2010-2015 BMW 550i GT Base 2010-2017 BMW 550i GT xDrive Base 2011-2016 BMW 550i xDrive Base 2004-2005 BMW 645Ci Base 2006-2010,2012-2018 BMW 650i Base 2013-201
