CTS Turbo is proud to announce our Front Mount Heat Exchanger for the BMW F-series B58 platform.

The factory front-mounted heat exchanger is small and not efficient enough to provide enough cooling to tuned Fxx B58 engines. We designed our heat exchange to overcome that problem. The double-pass core was made to be higher flowing and larger than the factory but still drop into the stock location. CNC machined mounting points and hose connections allow for a seamless install without any need to cut or trim any factory parts.

We also included a handy vent to allow you to easily bleed any air out of the cooling system after the installation.

Keep your B58 running cool and reliably with CTS Turbo Front Mount Heat Exchanger.


  • CNC machined mounting points and hose connection for factory fitment
  • Drop-in design
  • Smooth bends on the coolant connections
  • High-efficiency double-pass aluminum core
  • Hand-welded and pressure tested
  • Lowers intake air temperature
  • Installation hardware included (transmission cooler relocation brackets)
