CSF 06-10 BMW E60 M5 / E63 / E64 M6 Race-Spec Oil Cooler

The original OE oil cooler from BMW is an all-metal design, which might lead you to believe it would be fairly robust. However, there are several weak points in the design that tend to cause leaks. The CSF Race-Spec design reinforces these weak points, especially around the feed and return lines. CSF's solid line connection block can handle any abuse thrown at it, while the reinforced and braced return tube is rock-solid. CSF also upgraded the more fragile tube-and-fin core to a robust and durable bar-and-plate design. The core is 40% larger than the factory unit, with 2 additional rows of oil cooling and a much thicker core (63 mm vs. OE 45 mm). This provides superior cooling capacity and volume for the oil system. TIG-welded end tanks round out the extensive upgrades, creating a much stronger connection than the factory-brazed construction.
