CSF High-Performance Transmission Oil Cooler (2018-2022 BMW 330e, M340i & M340ix, 2018-2022 BMW M340ix, 2018-2022 BMW M40i & 2020-2022 GR Supra)

CSF is the world leader in cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies.

An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions - from road racing to the drag strip.

During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use.
