NOTE: BMW superseded the two oil lines on E9X M3s built around and prior to 03/08, and CSF oil coolers require the use of the current-spec BMW oil lines (17222284077 & 17222284078).

The CSF E9X M3 Oil Cooler is also compatible with all surrounding modifications in which the factory cooler is applicable. Whether you have a supercharger or you are simply looking to add reliability with vastly improved oil cooling to your factory-spec M3, this oil cooler will help keep your oil temperatures in check, whether in demanding, on-track conditions or sitting in traffic.
