The 2006-2010 BMW E60 M5 combines the spacious practicality of a four-door sedan with a naturally aspirated V10 powerplant producing a hypnotic soundtrack of intake/exhaust noise. But after over a decade of use, some of the E60's components have begun to show their age. The factory engine oil cooler is a common leak point on the E60, typically from failed O-rings or cracked weld points. In addition, the location of the front-mounted cooler increases the chance of damage from road debris and general clogging of external fins, resulting in reduced cooling efficiency. That, combined with the high-strung engine and hefty chassis, means oil temperatures tend to rise during aggressive driving. That's why our engineering team set out to remedy both issues with this performance oil cooler
