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

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)
