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

Description
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 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+ F8X and G8X thermostat is backed by our Mishimoto Lifetime Warranty.

Well worth it.

Just bought these clears for my mk7 and love them already. took under a hour to install and i feel like it was a much needed addition for my car. only thing i will say is if you buy them be aware that you have to take your reverse bulb out of your stock tail lights and put them into these (takes 30 seconds to get them out and put them in these new ones) follow my ig: dstagetwo ;)

Completely changed the look!

I love these headlights, I wouldn’t hesitate to buy them again if I got another truck my body style. Best looking headlights I’ve seen that they make for this truck.

Great little side marker!

GreEasy to install on my E46 M3 and it looks more modern with the LED lighting. Yes, the light does stay on for a minute (or two) after I un/lock it but it actually looks pretty cool. Definitely an easy modification to update your car's look.
