The do88 performance radiator is an all-aluminium unit with uninterrupted welds that solves the rising coolant temperatures common to the S65 V8 in the E90, E92 and E93 M3. Its dual-core 2-row 41mm core with 6.3mm multi-louvered fins holds 11,193 cm3 of coolant, 14% more than the OEM radiator, and lowered the measured outlet temperature to 73C against 79C for the stock unit under identical conditions. CNC-machined quick-connections and mounting brackets make it a direct drop-in using the factory hoses, brackets, fan cover and AC condenser.
