***Product Update October 2019 Production*** CSF’s pursuit of cooling perfection continues with improvements to The Ultimate BMW B58 High Performance Heat Exchanger. As of October 2019, CSF has released a new and improved “Version 2.0” of the BMW B58 Heat Exchanger. Improvements include the following three (3) key updates:

 

  • Upgraded Inlet/Outlet Design with New Tapered Entry and Exit Points from End Tanks, Resulting in Optimized Water Flow and Increased Performance (Matches OEM Spec)*
  • After Extensive Wind-Tunnel, Dynamometer (Rolling-Road Test), and Field Testing, CSF Engineers Have Improved the Core Spec from Version 1’s 68mm 2-Row Core with 8mm Fin Height to Version 2’s Ultra-Efficient 42mm 2-Row Core, with CSF’s B-Tube Technology, and 6.5mm Multi-Louvered Fin Height*
    • Increase of 15% More Cooling Tubes Used in the Core vs. V1 Design for Better Surface Area Contact and Heat Dissipation
    • Results in Optimized Airflow Through the Heat Exchanger Core and Into Other Cooling System Components for Maximum Performance of the Entire Cooling System (Especially Critical if Installed in an X-Drive Model with Transmission Oil Cooler Placed in Front of Heat Exchanger)
    • CSF V2 Design: 2-Row 42mm Core vs. OEM Design: 1-Row 26mm Core. ~62% Increase in Core Fluid Capacity
  • Now Includes Hardware Mounting Kit* for Applications That Have a Factory Transmission Oil Cooler Mounted in Front of the Heat Exchanger (X-Drive Models) 
  • OEM #: 17118625431
  • CSF upgraded the inlet/outlet design and improved the core specifications for better air-flow, water-flow, and improved cooling system performance. These updated features result in further lowering Intake Air Temperatures (IATs) of the air-to-water in-manifold charge cooler air cooler system for maximum performance.
