Collection: Koyo (Koyorad)

Founded in 1969 in Japan, Koyorad started as a small radiator manufacturer focused on high-quality cooling solutions for Japanese vehicles. They gained recognition in the import tuner and motorsports communities, particularly with Nissan, Toyota, and Subaru platforms, for producing aluminum radiators and oil coolers that could handle high-performance and turbocharged engines. Over time, Koyorad expanded into a globally respected brand, trusted by street tuners, track racers, and professional teams for durable, race-proven cooling systems that maintain performance under extreme conditions.
