CTS Turbo F-series B48/B58 BMW 230i/330i/430i/M140i/M240i/340i/440i Heat Exchanger Upgrade

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.

• CNC machined mounting points and hose connection for factory fitment
• Drop-in design
