Koyo HH Series Aluminum Radiator + N-FLO 89-94 Nissan 180SX/ S13 Silvia 2.0L TBO I4 (MT)

This radiator features Koyorad's "HH Series" 48mm radiator core which was developed to increase coolant volume, promote proper air flow and coolant circulation.

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.

NOCOLOK R Brazing

Nocolok Brazing is used in all Koyorad Racing Radiators. This ensures maximum durability, strength and anticorrosion protection. Nocolok Brazing uses anticorrosive flux, encouraging even flow of over fins and tubes forming a strong bond in our furnace. With over 50 years of experience in manufacturing OE replacement radiators certifies our consistent high quality and durability.
