Description
Keep transmission and engine oil temperatures under control with the CSF Race-Spec Transmission/Oil Cooler, engineered specifically for high-performance BMW applications. Whether you're driving aggressively on the street or pushing your vehicle on the track, this race-proven cooler delivers approximately 30% greater cooling efficiency compared to the factory unit, helping protect your transmission and engine from excessive heat.
Built using CSF's advanced AC Condenser Technology, this premium cooler features a 1-row, 22mm super-high-pressure, 11-channel microtube core combined with a dual-pass high-performance design for superior heat dissipation. Compared to the factory cooler, the CSF unit utilizes 11 cooling tubes instead of 10 while incorporating a high-density multi-louvered fin design that increases surface area contact by approximately 20%, maximizing cooling performance under demanding conditions.
Designed as a true plug-and-play upgrade, this cooler installs directly in place of the factory unit without requiring any modifications. It accepts all original mounting hardware, oil-line connections, brackets, shrouds, and ducting, making installation straightforward while maintaining OEM fitment.
For BMW E9X M3 models equipped with the DCT transmission, this unit functions as a high-performance transmission oil cooler. On 6-speed manual (6MT) E9X M3 models, it can be used as an engine oil cooler, offering exceptional versatility for enthusiasts and racers alike.
