CSF BMW F8X M3/M4/M2 Comp & F9X X3M/X4M High-Performance Engine Oil Cooler

Keep oil temperatures in check as you push your S55 F8X M3/M4/M2 Competition or S58 F97 X3M / F98 X4M hard on the street or track. The CSF High-Performance Engine Oil Cooler delivers roughly 30% more cooling efficiency than the factory unit with a true factory-style fit.

Design & Engineering

This cooler uses CSF's AC Condenser Technology: a 1-row super-high-pressure 10-channel microtube for optimal oil flow and maximum surface-area contact. The 32mm core offers 15% more core volume than the OE 28mm core.

It keeps the factory mounting location and dimensions, so the factory ducting and shrouds are reused with no modifications. A removable/replaceable rock guard helps protect the cooler from road debris.
