The do88 power steering oil cooler is a direct replacement for the undersized factory servo cooler on the E90, E92, and E93 BMW M3, targeting the power steering fluid overheating that plagues these cars on track. Its core volume grows to 1562 cm3 from the OEM 432 cm3, active cooling area doubles to 578.5 cm2, and oil capacity rises to 200 ml versus 100 ml stock. It bolts in using the factory oil lines and mounting brackets with no modification required, making it a straightforward upgrade for track days, endurance racing, and spirited street driving.
