For cars built around and prior to 03/08 you may need to upgrade your oil lines. BMW superseded oil lines on early vehicles and they are physically different. The CSF oil cooler is designed for vehicles with the later spec lines. These oil lines are available direct from CSFor from your local BMW dealer.
