Koyorad carefully welds aluminum partitions in the upper and lower tanks of the radiator.  This is Koyorad’s N-Flo Technology which allows for a double or triple pass radiator. This design cools more efficiently by allowing the coolant to remain in the radiator for a longer period of time therefore transfering more heat to the surrounding air.  N-Flo Technology is available on cars that are known to have limited airflow to the radiator
