Koyorad is proud to introduce the very first high-performance radiator for the 2017 Honda Civic Type R.  This brand new application features Koyorad's high density Hyper core.  This core was selected to increase the thickness of the stock radiator by over 50% to boost the Type R’s heat capacity and endurance which is especially helpful during track conditions.  In addition, the all-aluminum construction replaces the weak plastic tanks found on the stock unit.  Koyorad has engineered this radiator with precision, to directly replace the stock OEM radiator, maintaining provisions for the factory fans, fan switch, A/C condenser, and accepts OEM hoses for a quick and simple installation. Koyorad’s advanced engineering and design methods, impeccable welds, experienced furnace brazing, and triple pressure testing for quality has earned their excellent reputation in performance cooling worldwide.



• High Density fully brazed Hyper Core

• Precision TIG welded

• Two Row construction

• Brushed aluminum finish

• Direct Fit with OEM fans, hoses and sensor

• Billet Drain plug
