Koyorad Alloy Radiator Mazda RX8 13B-MSP SE3P 53mm Core

Koyo's "R" Series aluminium radiators feature an all-aluminium core brazed to polished aluminium end tanks for a show quality finish. Koyo uses state of the art Nocolok Brazing Furnace to bond all of the radiator brackets, headers, tubes, and fins, creating high quality "indestructible" radiator. All aluminium end tanks are hand crafted using the latest Heliarc Soldering technique for the most reliable connections, then polished to a mirror finish. Over 60 applications are available for Koyo "Racing" series.

All Koyo Racing series radiators have "OE Specification" mounting location for stock mounting without major modifications; however we recommend using aftermarket electric fans for the best results. Koyo Hyper Radiator Caps are also available to increase your cooling system pressure to 1.3 bar for increased cooling capacity. Racing series radiators were made for manual transmission only, however with a separate automatic transmission cooler; one can use the Koyo Racing Radiator with automatics for increased cooling capacity.

When factory equipped radiators have inlet and outlet locations that allow proper placement,  Koyorad carefully welds aluminium 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 Aluminium 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.
