CTS Turbo is proud to announce our Front Mount Heat Exchanger for the BMW F-series B48/B58 platform. Now in our updated black finish! The factory front-mounted heat exchanger is small and not efficient enough to provide enough cooling to tuned Fxx B48/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. We also included a handy vent to allow you to easily bleed any air out of the cooling system after the installation. Keep your B48/B58 running cool and reliably with CTS Turbo Front Mount Heat Exchanger. Features:
  • 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)
