The original radiator mounting provisions are retained along with the ability to use the OEM fan shroud and coolant hoses, requiring no modifications to install. Koyorad’s advanced engineering and design methods, impeccable TIG welds, proficiency in furnace brazing, and triple pressure testing for quality have earned their excellent reputation in performance cooling worldwide.
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 Koyorad 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.
