N-FLO Technology

When factory equipped radiators have inlet and outlet locations that allow proper placement,  Koyorad carefully welds aluminium 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 transferring more heat to the surrounding air.  N-Flo Technology is available on cars that are known to have limited airflow to the radiator. Unless noted otherwise, all Koyorad N-Flo Aluminium Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the  stock fan shrouds and fans.  See notes in individual item descriptions for details.
