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. 

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.  

HYPER V SERIES 36mm Core Thickness with Hyper Fin and Tube Pitch

The Hyper V-Core Series is the newest to the Koyorad | Koyo All Aluminum Racing Radiator line up.  An engine's cooling system in many newer vehicles are suffering due to limited space and crowding which affects air circulation.  Our new ultra efficient Hyper V core was developed specifically for vehicles which see extreme heat, are limited in space, and where the factory inlet/outlet locations eliminate the option for a proper N-FLO design.   The Hyper V Series radiators have a specially designed fin and tube pitch which significantly increases its surface area while still allowing for excellent air circulation through the radiator.  The Hyper V-Core series is the perfect solution where space savings and high performance is a must.   Unless noted otherwise, all Koyorad Hyper 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.  

S SERIES Copper Core

S Series radiators incorporate the same technology as Koyo's OE aftermarket replacement product line; Moulded plastic tanks but with a copper core in place of aluminum.  Due to the excellent heat exchange properties of Copper, Koyorad S Series radiators are a great choice for a light tuned car, when it will not be at speed for extended lengths of time.  All Koyorad S Series 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.  S Series Copper Radiators are available for Nissan S13 with SR20DET, S14/S15 with SR20DET, and Honda DC2 Integra vehicles.

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.
