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.
Designed for BMW F8X M3 (F80), M4 (F82/F83), and M2 Competition (F87) with DCT transmission.
Compatible with S55 3.0L twin-turbo engines in the vehicles listed above.
Replaces the OEM transmission cooler (BMW #17112284503) directly without modification.
Direct “drop-in fit” — accepts all OEM mounting brackets, oil-line connections, and ducting.
Ideal for street performance and track use, especially where DCT fluid temperatures rise under repeated high-load driving.
Race-spec DCT transmission cooler assembly with dual-pass core.
OEM-compatible mounting provisions (hardware varies by dealer).
Installation guidance (varies by retailer).
