This product is installed in the BMW oil cooler system thermostat
It can make the oil temperature control between 90 degrees C to 110 degrees C
(for BMW N54 N55)
When I driving in high way,
I use the SGEAR low oil temp thermostat
, the oil temp is maintained at 90~100 Celsius , very nice
When racing in the Racing track
Oil temperature is also controlled at the Celsius temperature of 100 ~ 110
This device is very good for oil temperature control
