CSF B58 High-Performance DCT Transmission Oil Cooler

Keep your automatic transmission cool and shifting hard with the CSF High-Performance Transmission Oil Cooler. CSF is the world leader in BMW transmission cooling, and this cooler carries over the technology they developed for the F8X M3, M4, and M2 Competition programs. The ZF8HP automatic in these cars runs hot under sustained load, and once trans fluid temps climb the car pulls timing, softens shifts, and can drop into a reduced power limp mode. This cooler solves that.

The key is CSF's innovative dual core design, which delivers a 240 percent increase in core volume over stock. That massive jump in cooling capacity keeps fluid temperatures in check during repeated pulls, track sessions, and aggressive street driving, so the transmission keeps shifting crisply when a factory setup would be heat soaked.

It is engineered as a true drop in fit. The cooler works with either your OEM front mount heat exchanger or CSF's high-performance version (CSF 8154), and it reuses the factory top and bottom rubber seals so airflow into the cooling stack stays optimized. No cutting, no compromises.

Note that this cooler is for the ZF8HP automatic transmission cars. Confirm your model and transmission before ordering.
