Koyo aluminium performance radiators are engineered as direct-fit replacements for the factory radiator, with increased cooling capacity and durability for demanding use. Each unit is designed to maintain stable coolant temperatures in street, track day and competition environments, while retaining factory mounting points and hose connections for straightforward installation. Made in Japan.

The EG and EK Civic family — including the Civic Ferio, CR-X, and Domani — are some of Honda's most beloved lightweight platforms. Whether you're running a stock D-Series daily or a built track car, the Koyorad HH080292 delivers the cooling performance your build deserves in a direct bolt-in package.
