The latest from Koyorad is this all-aluminum performance radiator for the 1968-1972 Nissan Skyline “Hakosuka” KGC10 with the L20 engine. This all-new application is hand-welded and fully braised with an over 40-percent increase in core thickness over the OEM radiator. The high-density Koyorad hyper core boosts the cooling system’s heat capacity and endurance; a perfect upgrade for spirited street driving or track use. The Skyline’s 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 the company its excellent reputation in performance cooling worldwide.
