BMW Radiators & Cooling System Overhaul Kits

We sell only OEM Behr, Original BMW, or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used too many weak materials like plastic for critical connections. The core and sizing of the radiators are generally sufficient for the intended application but problems can occur at hose connections, upper or lower necks, and plastic end tanks. The radiators we sell are all OEM designs to keep the quality high. In some cases the OEM has made design improvements to prevent past issues. There are a number of non-OEM replacement radiators that use even cheaper materials and poor workmanship which only leads to more problems. On some models we offer OEM alternatives that perform as upgrades to the original designs and we also offer full race all-aluminum radiator upgrades that solve all of the issues with plastic radiators.
