Product Information

The BigPack gathers do88's complete cooling range for the S65 powered M3 into one package: the aluminium radiator, the racing engine oil cooler, the power steering oil cooler and the DKG/DCT gearbox 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, and dropped oil temperature from 103°C to 84°C. The 18 row gearbox oil cooler holds 2,208 cm³ against 696 cm³ and cut gearbox oil temperature from 90°C to 74°C, while the power steering cooler carries 200 ml against the OEM 100 ml. Every part is a drop-in fit on OEM lines, brackets and hoses with CNC machined connections.
