CSF DCT Transmission Cooler for BMW F80 M3, F82 M4, and F87 M2 Competition

Description

The CSF Race-Spec DCT Transmission Cooler is a plug-and-play performance upgrade for BMW F8X M3, M4, and M2 Competition models equipped with the dual-clutch transmission (DCT). Built to significantly outperform the restrictive factory cooler, this high-efficiency unit helps maintain lower transmission temperatures during spirited driving, track sessions, or heavy street use — reducing thermal stress on expensive transmission components and preserving shift quality under load. Utilizing advanced heat-exchanger technology adapted from high-end AC condensers, the CSF cooler delivers noticeable temperature control improvements without complex installation, making it a smart reliability-focused upgrade for any enthusiast pushing their S55-powered BMW to its limits.

Fitment Notes

• Designed for BMW F8X M3 (F80), M4 (F82/F83), and M2 Competition (F87) with DCT transmission.
