CSF BMW F87 M2 Race-Spec Dual-Pass DCT Cooler

CSF #8103 Race-Spec Dual-Pass DCT Cooler is a high-performance transmission cooling upgrade developed specifically for the BMW F87 M2 with the N55 engine and DCT transmission. It is designed to help manage DCT oil temperatures during demanding street and track driving.

The cooler uses CSF's AC Condenser Technology with a 1-row, super-high-pressure 26mm multi-channel microtube and a high-density multi-louvered fin design to maximize heat-transfer efficiency.

Its Dual-Pass High-Performance Core changes the flow design from the OEM single-pass configuration with a 6-tube return pipe to a dedicated dual-pass design. CSF lists 10 cooling tubes for the current product specification.

CSF laboratory testing shows approximately 30% greater cooling efficiency than the OEM cooler under its specified test conditions. Earlier CSF development material reported approximately 40%+ efficiency improvement, so the current official product specification is best represented by the approximately 30% figure.

The #8103 is engineered as a Drop-In Fit, retaining the OEM oil-line connections, mounting brackets and factory shroud/ducting. Installation requires no vehicle modifications.

The cooler is specifically developed for the BMW F87 M2 N55 DCT, with CSF listing an application range of 2016–2018. The product replaces OEM transmission cooler part number 17 21 2 409 076.

For drivers who regularly push the F87 M2 on track, improved DCT thermal management can help maintain more consistent transmission temperatures under sustained load, making the CSF #8103 a focused cooling upgrade for the N55 DCT system.
