The CTS Turbo Front Mount Heat Exchanger is a high-performance cooling upgrade engineered specifically for BMW S55-powered vehicles, including the F80 M3, F82/F83 M4, and F87 M2 Competition and CS (2014–2021). Designed to address the limitations of the small and inefficient factory heat exchanger, this unit features a high-efficiency double-pass aluminum core that significantly improves cooling performance, making it ideal for tuned or aggressively driven S55 engines. Its larger surface area and optimized flow design help maintain lower intake air temperatures, reducing the risk of heat soak and ensuring more consistent power output during spirited driving or track use.
Precision CNC-machined mounting points and hose connections ensure a direct OEM-style fit without the need for cutting, trimming, or custom fabrication. This drop-in replacement for BMW part number 17112284608 also includes an integrated air bleed valve, making it easy to eliminate trapped air from the cooling system after installation. Each unit is hand-welded, pressure-tested, and engineered not to obstruct airflow to the radiator or air conditioning condenser, preserving daily drivability and reliability. Whether you’re pushing your S55 engine on the street or the circuit, the CTS Turbo Front Mount Heat Exchanger is an essential upgrade for maximizing cooling efficiency and long-term engine performance.
