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

The fit is perfect. The material is quite nice. The only problem would be they are hard to de-wrinkle from original packaging. I’ve washed my shirt several times and it’s still showing the creases. The only way to get rid of them is to launder them or iron them. I think once this occurs, they remain wrinkle free for a while. This is the third of the exact same shirt I got in different colors.

Nice quality shirt

Color: Purple, Size: XX-Large

Nice material and fit is accurate. However shirts are rolled up in a tube, so if you need to wear the shirt the day you receive it be prepared to iron it!

Calidad de las camisas

Color: A White, Size: Medium

I had already bought one shirt, so this time I bought two more. The light blue one is the same quality as the one I bought the first time. But the white one wasn't the same quality. It was also a different shade of white. They should try to maintain consistent quality across the board.
