The R-Core Series boasts an impressive 53mm core thickness, meticulously crafted to cater to the demands of dedicated performance enthusiasts. This robust core signifies expanded cooling capacity, ensuring you have ample cooling reserves when pushing your vehicle's limits. Whether you're hitting the circuit or driving daily, this radiator can double your coolant capacity, potentially delivering up to a remarkable 35% boost in performance compared to your factory radiator. Koyorad's R-Series All Aluminum Radiators, unless explicitly specified, are Nocolok brazed and designed for a seamless factory fit. They are direct bolt-ins requiring no engine modifications and conveniently retain the mounts for your stock fan shrouds and fans.

N-FLO Technology:

For vehicles with factory radiators featuring inlet and outlet locations that demand specific placement, Koyorad expertly integrates aluminum partitions into the upper and lower tanks of the radiator. This engineering marvel is referred to as Koyorad's N-Flo Technology, allowing for the creation of a double or triple pass radiator. This innovative design drastically improves cooling efficiency by retaining the coolant in the radiator for an extended duration, facilitating greater heat transfer to the surrounding air. Similar to the R-Series, all Koyorad N-Flo Aluminum Radiators, unless otherwise specified, are Nocolok brazed, specifically designed for an effortless factory fit, require no engine alterations, and maintain the mounts for your stock fan shrouds and fans.
