do88 BMW M3 E46 Front Mount Radiator

This radiator is constructed to deliver the best possible cooling efficiency during tough conditions. Exclusively manufactured in aluminium with uninterrupted welds, it guarantees genuine reliability and endurance when you really need it, whether that's a track day, endurance race, or simply spirited street driving.

The numbers: a 17% larger core volume than the factory unit (11,736cm³ versus 10,068cm³), using a genuine triple-pass design that controls water flow so it passes through the radiator core three times, maximising contact time with the cooling fins for the lowest achievable outlet temperature. Deliberately designed without quick-connections, a choice made specifically for best function in racing, where those connections can be a genuine reliability weak point. New hoses and a Bosch temperature sensor are included, along with a take-out for an extra temperature sensor (M12x1.5), useful for controlling an electric fan if you're running one. The radiator is also prepared with mounting brackets on the front specifically for do88's own auxiliary oil cooler, sold separately, letting you build out a complete cooling system around this radiator.

Works with: Drop-in installation, see installation instructions for your specific application. Compatible with do88's Auxiliary Oil Cooler (mounts directly using included brackets), sold separately.
