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

Keep your tuned F-series B48/B58 BMW running cool with the CTS Turbo front-mount heat exchanger, now in an updated black finish. The factory unit is small and runs short on cooling capacity once you tune — this larger, higher-flowing double-pass core drops into the stock location and keeps intake air temperatures in check.

Why it works

• High-efficiency double-pass aluminum core, larger and higher-flowing than factory
• CNC-machined mounting points and hose connections for factory fitment
• Drop-in design with smooth bends on the coolant connections — no cutting or trimming
• Hand-welded and pressure tested
• Lowers intake air temperature
• Installation hardware included (transmission cooler relocation brackets)

Fitment
