CTS TURBO F-SERIES B58 BMW M140I/M240I/340I/440I HEAT EXCHANGER UPGRADE

CTS Turbo Front Mount Heat Exchanger for BMW F-Series B58

Keep your tuned B58 engine cool and running reliably with CTS Turbo’s Front Mount Heat Exchanger, engineered specifically for the BMW F-series B58 platform.

The factory front-mounted heat exchanger is undersized and struggles to provide adequate cooling for high-performance, tuned B58 engines. CTS Turbo designed this upgraded heat exchanger with a larger, high-flow double-pass core that fits perfectly into the stock location — no cutting or trimming required.

Key Features:

• CNC-machined mounting points and hose connections for seamless factory fitment

• Drop-in design ensures easy installation

• Smooth coolant connection bends for optimal flow

• High-efficiency double-pass aluminum core for superior heat dissipation

• Hand-welded and pressure tested for reliability

• Includes transmission cooler relocation brackets and installation hardware

• Convenient vent to easily bleed air from the cooling system post-install

Performance Benefits:

• Significantly lowers intake air temperatures

• Maintains cooler coolant temps under heavy loads and tuning demands

• Supports reliable, consistent performance in tuned Fxx B58 engines

Vehicle Fitment:

• BMW M140i/M240i B58 (F20/F21/F22/F23)

• BMW 340i B58 (F30/F31/F34)

• BMW 440i B58 (F32/F33/F34)
