The new CSF Engine Oil Cooler is a great addition to the already popular BMW X3M / X4M  - F97 / F98 S58 Cooling Suite. Like the other cooling systems on the F9X, the factory oil cooler does a pretty good job in stock form. However, once you start adding a lot of power and pushing the car in aggressive driving conditions, the factory systems start to show its limitations. As more and more owners have pushed the limits of their S58, CSF saw the need and demand.
 
When designing this new cooler, CSF wanted to ensure the best possible performance with factory like fitment. This oil cooler is a truly unique design using CSF’s AC Condenser Technology. The 1-Row Super-High Pressure 32mm 10-Channel Microtube provides optimal oil flow and maximum surface area contact.
By keeping the factory mounting location and relative dimensions, the factory ducting and shrouds are all reused with no modifications necessary. In addition, CSF added a removable/replaceable rock guard to keep the cooler safe. You’ve no doubt heard horror stories about an OEM cooling getting punctured and spilling oil all over the road or track. Now you can feel safer and more confident that your oil system is safe from road debris.
