All-Aluminum Race Radiator by Koyo

Koyorad released a high-performance radiator for the 2008-2013 BMW M3. This all-aluminum upgrade features Koyorad's 48mm thick, high density Hyper core, offering a 20% increase in thickness compared to the OEM unit. The added coolant volume and all-aluminum construction boosts the M3’s heat capacity while also replacing the weak plastic tanks found on the stock radiator. Extensive development and testing allows for an easy installation by directly replacing the OEM radiator. It maintains OEM provisions for the factory fans, and accepts the vehicle’s OEM coolant hoses, requiring no modifications. Koyorad is well known for its advanced design methods, impeccable TIG welds, proficient core brazing and quality assurance triple pressure testing which distinguish Koyorad as a global cooling manufacturer.
