R SERIES 53mm Core Thickness
Built with a robust 53mm core, the R-Core Series 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. Unless noted otherwise, all Koyorad R-Series 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. See notes in individual item descriptions for details.
V SERIES 36mm Core Thickness
Designed for applications where engine configuration/size cause clearances issues for thicker core radiators. In this case, the 36mm V-Core Series will suit your needs. Intended for both circuit and daily use. Unless noted otherwise, all Koyorad V-Series 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. See notes in individual item descriptions for details.
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.
