The ZF 8HP behind the B58 runs an external liquid to air transmission cooler from the factory, and on tuned cars that cooler runs out of capacity on track, on the strip and in hard street use. do88 redesigned the core to raise volume by 184% and active cooling area by 176% while holding similar fluid pressures, using harmonica tubes with internal channels for oil flow and surface contact. The inlet and outlet keep the OEM style quick connect fittings so it is a drop-in change with no modification, and it is compatible with the do88 WC-400 front intercooler radiator.
