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 let it bolt in at the factory mounts using the factory hoses, brackets, fan cover and AC condenser, although do88's installation instructions call for trimming three small plastic edges (about 5mm long) on the left-hand radiator support before fitting.
