If your factory radiator is leaking or just isn't cutting it anymore under the hood of your performance vehicle, Koyo offers quality direct replacements and upgraded aluminum racing radiators that will keep your engine cool while retaining the factory fan shroud. They are remarkably affordable for high-performance radiators, especially for such a well-respected aftermarket brand. In our opinion, you can't go wrong with a genuine Koyo radiator.

Koyo manufactures its own radiators in its own factories, unlike many companies that outsource their manufacturing to third parties. Because of this, Koyo is able to maintain a high level of quality control on all of its products, guaranteeing a perfect radiator every time. In our experience, Koyo radiators fit and install just like your factory original radiator, unlike some lesser brands that can require some modifications to fit just right.

These radiators are designed, manufactured to original equipment specifications. Koyo, the largest aftermarket radiator manufacturer in Japan, produces these radiators from aircraft quality aluminum and are Heli-arc welded.
