Removing OEM heat exchanger, fluid drained was green.
I added new green HT12 taken from the dealership.. To my knowledge it only uses one type of coolant and not two
Humidity cleared and wanted to compare IAT in stop & go traffic dry weather both days 48C temps
Left: CSF
Right: OEM
5C temp difference between the two :thumbsup:
To be completely honest, if you want something for the track a custom tune is the way to go.. Car will actually be begging for one
Ecutek and someone knowledgeable who must know the car does track duties
Also, do heat exchanger upgrade :thumbsup: Less heat soak after WOT pulls
