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 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 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)
Vehicle Fitment:
- F20/F21/F22/F23 BMW M140i/230i/M240i
- F30/F31/F34 BMW 330i/340i
- F32/F33/F36 BMW 430i/440i
- Replaces BWM Part#: 17118741830
