Koyorad Comes Back to Roadster Cup!

Please help us welcome back Koyorad, they will be partnering with Roadster Cup for the 2016 season! When it comes to creating quality cooling products, Koyo flows with craftsmanship and performance. Koyorad is also celebrating its 60th anniversary this year and we’re happy to celebrate with them! Below you will find a little background and why we think they’re so…cool! Get it?


Koyo is a Japanese company established 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.

In Japan we have more than 20 engineers backed with over 54 years of experience.  This ensures that our customers receive products of the best quality, performance, and fit. We at Koyorad strive continuously to find ways to improve and implement new technologies in our Radiators and Condensers.

Koyo uses only Japanese made equipment and sources only the finest Aluminum when producing our products. The combination of skilled engineers, quality materials and precision manufacturing is what has earned Koyorad its reputation for performance and reliability.

Before any new model is introduced to the market, we test extensively for fit, finish, and performance.  From installation to road testing, when you purchase a Koyorad Racing Radiator, you are getting a superior quality product that is built to last.

With decades of hand crafting experience, it is hard to beat our quality for precision and uniformity which is recognized by our customers worldwide.

Each class champion will receive an oil cooler for their Miata. Koyo also funded shirts that will be given to each driver. We couldn’t be more thrilled to start this year off with another familiar face behind the wheel. Thank you for your continued support, Koyorad!
