CTS Turbo is proud to announce our Front Mount Heat Exchanger for the Toyota Supra A90/91 and BMW G-series B46/B48/B58 platform. The factory front-mounted heat exchanger is small and not efficient enough to provide enough cooling to tuned  B46/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 without any need to cut or trim any factory parts. Keep your B46/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
  • Fully compatible with factory rock guard, simply transfer the factory parts over
  • Replaces OE#: 16400-WAA03 and 17118666811
