SKU: 8042

All orders will include an AutoTalent window decal


This CSF upgraded oil cooler for the DCT transmission has a better cooling efficiency than the factory cooler. Better cooling performance reduces the potential for a DCT-related failure or interruption. The stock oil cooler design allows one to pass through the cooling fins and then returns via an external pipe. BMW wasted an opportunity to return the oil through the cooler again.

CSF recognized this drawback and their Dual-Pass cooler allows the oil to pass through more cooling surfaces to further reduce temperatures. The CSF has double the number of tubes of the stock cooler! Hot oil such as from track driving can send DCT oil temperatures over the limit and force a shutdown or limp mode. This CSF DCT cooler reduces the potential for that and lets you get on with your track day.


  • Made with CSF’s AC condenser technology using a 1-row super-high pressure 26mm multi-channel microtube
