Koyo is a Japanese company established in
July of 1956 as Ejiri Radiator in Nagoya, Japan (Aichi Prefecture) as a
radiator repair shop. Twelve years later in 1968, Ejiri Radiator
established a radiator and oil cooler factory in Nagoya. We then
separated our production facilities from our repair facilities and began
manufacturing radiators. Two years later in 1970, Ejiri Radiator was
renamed to Koyo Radiator Manufacturing and began expanding to branches all over
Japan. Koyorad quickly developed into an industry leading Aftermarket
Radiator Supplier worldwide. With over 57 years of radiator design and
manufacturing experience, founder Mr. Ejiri and son soon gained interest in
automotive racing.
Officially launched in 1999 in Japan, Koyorad Racing Radiators soon made a
presence in Japan’s ever popular racing scene. Koyorad Racing Radiators
soon became synonymous with Koyo’s High Quality Aftermarket Radiators. As
Koyorad Racing Radiators grew in reputation for quality and performance, so did
the company’s desire to expand. In 2004, Koyorad Racing Radiators made
it’s US debut. What started as a few racing applications for Japanese
vehicles in 2004 has now in 2013 grown to over 80 models for Japanese, US Domestic,
and Korean vehicles.
