Koyorad is proud to introduce an all-aluminum performance radiator for the 2006-2008 Mazdaspeed 6.

The high density 36mm Hyper core measures over twice the OEM radiator thickness with densely arranged tubes and fins to boost heat capacity and endurance under extreme use. Advanced engineering and design methods allows for use of the vehicle’s factory fans, AC condenser, OEM hoses and OEM mounting provisions, requiring no modifications.

Impeccable TIG welds, proficiency in furnace brazing, and triple pressure testing for quality have earned Koyorad their excellent reputation in performance cooling worldwide.
