BMW Dual‑Clutch Gearbox Oil Heat Exchanger | F10 M5 • F06 F12 F13 M6 | M4 GT4 Spec
BMW Part Number: 17212284241
Serious track and fast‑road builds need dependable temperature control. This factory BMW gearbox oil heat exchanger, as run on the M4 GT4 programme, delivers outstanding thermal management for DCT cars driven hard on circuit. It is a direct BMW part for the F10 M5 and F06 F12 F13 M6 and a renowned upgrade when retrofitted to S55 dual‑clutch platforms looking for cooler, more consistent shift performance lap after lap.
Compared with the standard S55 cooler, this motorsport‑derived unit offers around a 30% increase in core volume and roughly an 18% larger frontal area, with a denser fin pack to shed heat faster under sustained load. The result is improved heat rejection, better gearbox oil stability and greater headroom for high‑demand use.
Why this BMW DCT heat exchanger stands out
- Genuine factory BMW component for perfect fit and build quality
- M4 GT4 specification hardware proven in endurance and sprint racing
- Bigger core and tighter fin matrix for stronger cooling capability
- Excellent choice for track days, time attack, drag and spirited road use
- Trusted by MJ Modifications and our customers for reliable temperature control
Note: The denser fin pack benefits from strong airflow. For heavy stop‑start commuting it offers less advantage, and as it mounts ahead of the radiator it is more exposed to debris. Sensible ducting and protection are recommended for harsh environments.
Vehicle applications
Direct fit dual‑clutch vehicles:
- BMW F10 M5 (2010–2016)
- BMW F06 Gran Coupe M6, F12 Convertible M6, F13 Coupe M6 (2011–2018)
Popular retrofit upgrade for S55 DCT cars:

- BMW F80 M3
- BMW F82 F83 M4
