Founded in 1956 in Japan as a small radiator repair shop, Koyo is now one of the largest and most trusted radiator manufacturers in the industry. They create the most reliable radiators and condensers on the market that are designed to meet, and even exceed, OE standards.
PRECISE TUBE/FIN ALIGNMENT
Construction under strict quality control and solid boxing result in tubes with optimal coolant flow and fins with highly efficient heat transfer.
NOCOLOK BRAZING
Nocolok Brazing is used in all Koyorad Racing Radiators (unless noted otherwise) to ensure maximum durability, strength, and anticorrosion protection. Nocolok Brazing uses anticorrosive flux, encouraging even flow of over fins and tubes forming a strong bond.
BILLET FILLER NECK
Precision machined billet filler necks are incorporated on each Koyo radiator for strength, durability, and better sealing.
HAND-CRAFTED HELIARC WELDS
Each Koyo All-Aluminium Race Radiator is Heliarc welded individually by hand. This creates the strongest aluminium to aluminium bond, to mate all components.
KOYORAD R-SERIES
Built with a robust 53mm core, the R-Core Series is engineered for the serious performance tuner. Increased capacity means better cooling reserve when you need it. Intended for both circuit and daily use, you may double your coolant capacity and see up to 35% increased performance over your stock radiator.
KOYORAD V-SERIES / HYPER V SERIES
The V-Series is designed for applications where engine configuration/size cause clearances issues for thicker core radiators. Intended for both circuit and daily use.
The new ultra-efficient Hyper V core was developed specifically for vehicles which see extreme heat, are limited in space, and where the factory inlet/outlet locations eliminate the option for a proper N-FLO design. The Hyper V-Series radiators have a specially designed fin and tube pitch which significantly increases its surface area while still allowing for excellent air circulation through the radiator. The Hyper V-Core series is the perfect solution where space savings and high performance is a must.
