Koyorad: Competition Radiators: Evo IV - VI (36mm / 53mm - Select Option)

V SERIES 36mm Core Thickness
Designed for applications where engine configuration/size cause clearances issues for thicker core radiators. In this case, the 36mm V-Core Series will suit your needs. Intended for both circuit and daily use. Unless noted otherwise, all Koyorad V-Series All Aluminium Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans.

R SERIES 53mm Core Thickness
Koyo's "R" Series aluminium radiators feature a 53mm (2 1/16 in) thick, all aluminium core brazed to polished aluminium end tanks for a show quality finish. Koyo uses state of the art Nocolok Brazing Furnace to bond all of the radiator brackets, headers, tubes, and fins, creating high quality performance radiator. All aluminium end tanks are hand crafted using the latest Heliarc Soldering technique for the most reliable connections, then polished to a mirror finish. Over 60 applications are available for Koyo "Racing" series.

All Koyo Racing series radiators have "OE Specification" mounting location for stock mounting without major modifications; however we recommend using aftermarket electric fans for the best results. Koyo Hyper Radiator Caps are also available to increase your cooling system pressure to 1.3 bar for increased cooling capacity. Racing series radiators were made for manual transmission only, however with a separate automatic transmission cooler; one can use the Koyo Racing Radiator with automatics for increased cooling capacity.
