Koyorad Racing

Koyorad 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.

In Japan we have more than 20 engineers backed with over 60 years of experience.  This ensures that Koyorad Racing Radiators are Best Quality, Best Performance, and Best fit.  We at Koyorad strive continuously to find ways to improve and implement new technologies in our Racing Radiators.
