Koyorad's 48mm “HH” Series radiator core features an ultra high fin density to maximize heat transfer. Koyo designs and manufactures each radiator with precision; therefore each one is a direct-fit performance replacement for the stock OE plastic/aluminum radiator for a quick and simple installation with no modifications. Koyo has also integrated a 1/8” NPT female accessory fitting (supplied with a threaded plug) to accept temperature sensors typically included with aftermarket temperature gauges.Koyorad quality is a direct result of their privately owned factories which allow Koyorad Japan to oversee each stage of radiator production. This ensures that quality is never sacrificed for quantity. Each Koyo all aluminum radiator core is hand assembled, Nocolok brazed, then TIG welded by hand with the finest aluminum available. These are just a few characteristics that have earned Koyorad Radiators their excellent reputation in performance radiators worldwide.Features* Koyorad “HH” Series 48mm Hyper Core* OE Specific mounting and direct fit* Nocolok-R Brazing* Precise Tube and Fin alignment* 1/8” NPT female accessory fitting

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 transfering more heat to the surrounding air. N-Flo Technology is available on cars that are known to have limited airflow to the radiator
Note: Re-use OEM Radiator Brackets
The Banzai Racing Stainless Steel FD Radiator Brackets are designed to be a direct replacement for the OEM parts. We get cars in all the time that are missing these brackets, Mazda will not sell them without the complete radiator assembly. Manufactured from laser cut Stainless Steel and press brake formed.
