Koyo 14-19 Ford Fiesta ST 36mm Hyper Core + NFLO Triple Pass Radiator

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.

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.  See notes in individual item descriptions for details.
