Koyorad leads the radiator industry in quality, performance, fitment, and extensive list of vehicle applications. Our quality begins with the careful testing in our R&D department, then to the manufacturing in Koyorad’s privately owned ISO 9001 certified factories, and finally to our class leading packaging. This process assures that each Koyorad OE aftermarket replacement radiator arrives safely and performs perfectly in the hands of the shop and end user. Our engineers carefully design our radiators offering a true plug and play installation: No drilling, cutting, relocating, or stretching to get our radiators to fit properly. When you buy a Koyorad radiator, you will receive a component that has been engineered to the highest standards.

Koyorad offers our experience of 56 years in the heat exchange industry and is renowned for manufacturing products of highest quality, performance, and fit-and-finish.  Koyorad has earned this exceptional reputation through our company’s strict quality control measures. Initially, Koyorad was the leading manufacturer of OE Aftermarket radiators in Japan.  After over 10 years in the US, we now offer the same level of quality for US and Europe markets.  Koyorad radiators are manufactured to the stringent quality and performance tests required by the OE’s, holding Koyorad to a much higher standard.  This makes Koyorad the obvious choice for your vehicle for the best reliability.
