CSF F1X M5/M6 and F9X M5/M8 High-Performance Engine Oil Cooler

The original OE oil cooler from BMW is an all metal design which would make you think it would be fairly robust. However, there are several weak spots in the design that make it far less durable than it could be. The CSF design resolves these issues with more robust materials and reinforcing weak points. At first glance, the original BMW OE oil cooler appears solid due to its all-metal construction. However, design weaknesses make it far less durable than expected. CSF tackled these flaws by using stronger materials and reinforced engineering to create a superior replacement:

• True Plug-and-Play "Drop-in Fit" Installation. It is recommended to trim the OE Ducting and Lower Radiator Cradle for better fitment.
• Developed with CarBahn Autoworks to handle the heat of their S63 Stroker Kit
• CNC Machined Mounting Brackets and OEM Style Inlet/Outlet Connection
• High Efficiency & Rugged Durability Bar/Plate Design
• Cast End Tanks with 100% TIG-Welded Construction
• Individually Leak and Pressure Tested
• 2-Year Limited Warranty
• Satin Black Finish
