CBF8X-2010 – CSF Auxiliary Radiators for S55

Like the other cooling systems on the F8X, the factory auxiliary radiators do 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 S55, CSF saw the need and demand. The F8X platform is also almost a decade old with the newest examples being at least 5 years old. Over time the original coolers end up with damaged or clogged fins that greatly reduce their cooling capacity. CarBahn is proud to offer CSF’s upgrade to this unit. The CSF Engine Oil Cooler includes: 

• 1 Auxiliary Radiator  
• Sold Individually – all applications require 2 auxiliary radiators. 
• Multi-Fit – Fits Both Left & Right Side 

OEM Part Numbers: 

• BMW: 17-11-2-284-603 / 17112284603 (Left) 
• BMW: 17-11-2-284-604 / 17112284604 (Right) 

Each CSF F8X Auxiliary Radiator can fit the left or right side. The fitting and plugs are swappable and can be easily set up for either side.
