The BigPack gathers do88's cooling range for the S65 powered M3 with a manual gearbox into one package: the aluminium radiator, the racing engine oil cooler and the power steering oil cooler. The radiator is a dual core 2 row 41mm design with a 6.3mm multi-louvered fin, holding 11,193 cm³ against the OEM 9,795 cm³ and running coolant at 73°C instead of 79°C in do88 testing. The 10 row bar-and-plate engine oil cooler holds 5,247 cm³ against 3,105 cm³ with 7,728 cm² of active area against 4,858 cm², and dropped oil temperature from 103°C to 84°C. The power steering cooler carries 200 ml against the OEM 100 ml with 578.5 cm² of active area. Every part is a drop-in fit on OEM lines, brackets and hoses with CNC machined connections.
