CSF BMW G8X M3/M4 High Performance Front Mount Heat Exchanger

The CSF High-Performance Front Mount Heat Exchanger for the BMW G8X M3/M4 is a proven solution to help combat heat soak and keep your S58-powered build running cool. Featuring a 2-row, 42mm thick core with CSF’s exclusive B-Tube Technology, this heat exchanger increases system fluid capacity and improves overall heat dissipation. The upgraded design also improves airflow into the radiator located behind the heat exchanger for enhanced cooling efficiency.

Designed with performance and protection in mind, this heat exchanger includes two black rock guards that cover both the upper and lower portions of the core — ideal for builds running popular "open face" race-style grilles. With over 100 hours of track testing and thousands of road miles logged, this drop-in upgrade delivers proven durability and performance for daily-driven, high-horsepower, or track-focused G8X builds. Optimized to work with CSF’s Race-Spec Dual Core Transmission Oil Cooler for ZF8 automatic transmission-equipped models.
