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 * Billet aluminum filler neck * 1/8” NPT female accessory fitting
