Koyo N-Flo Alloy Radiator - Nissan Silvia S13 / 180SX

Built with a robust 48mm core, Koyorad's all alloy radiator is engineered for the serious performance tuner.

Increased capacity means better cooling reserve when you need it. Intended for both circuit and daily use, you may double your coolant capacity and see up to 35% increased performance over your stock radiator. Koyorad's All Aluminum 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.

N-Flo Technology
When factory equipped radiators have inlet and outlet locations that allow proper placement,  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 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 Aluminum 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.
