Low-temperature thermostat for N63, N63TU, S63, S63TU, S55

Low-temperature thermostat for N62, N63, N63TU, S63, S63TU, S55

Hands down one of the best cooling modifications, i paired this with wetter water and my car has never ran cooler before. I live in Florida and this is the only way i was able to keep my engine temps down, paired with oil cooler.

Thank you guys !

The Low Temp. Thermostat works really well. Almost too well. I notice the incremental difference btw 100% stock; to only running the N63intake SOCV (sport oil cooler valve); to running the SOCV + LT Thermostat. It’s crazy. The valve is perfect for keeping the temps down but only when the car is moving, not too impactful in slow traffic and stop n go. But the thermostat completes it. I drove the car up n down for almost an hour and when I got to my destination I did an oil check before turning it off. I literally had to wait 2-3 seconds for the car to heat up at idle bc it runs so much cooler now. 1000% recommend both!!

Great product, have been using it for a few months and it has significantly reduced the temperature of my engine, both oil and coolant by (20°F) 2018 BMW M5
