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 Honda Civic EF and CRX are two of the most iconic lightweight Honda platforms — nimble, rev-happy, and endlessly tuneable. Whether you're running a stock D15B daily or a built ZC track car, the Koyorad KH080146 is a direct bolt-in upgrade that delivers the cooling performance your build deserves.
