The CSF Race-Spec Engine Oil Cooler upgrades the BMW E60 M5 and E63/E64 M6 from the fragile factory tube-and-fin unit to a robust bar-and-plate design that reinforces the weak feed and return line connections. The core is 40% larger than the factory unit with two additional cooling rows and a thicker 63mm core (vs 45mm OE) for superior cooling capacity. TIG-welded end tanks, a solid line-connection block, and a satin black finish round out the build.
