THE ULTIMATE COOLING SOLUTION FOR THE E46 M3


The CSF Race-Spec Engine Oil Cooler for the E46 M3 was designed, developed, and track proven in collaboration with BMW M3 tuning specialist and parts manufacturer, Rogue Engineering. Manufactured utilizing the latest in technology, the CSF oil cooler contains densely-packed cooling tubes to provide the greatest surface area for heat reduction in your high-revving S54 engine. 

The CSF oil cooler is also compatible with all surrounding modifications in which the factory cooler is applicable. Whether you have a supercharger or you are simply looking to add reliability with vastly improved oil cooling to your factory-spec M3, this oil cooler will help keep your oil temperatures in check, whether in demanding, on-track conditions or sitting in traffic.

Direct replacement for BMW part number 17212228942.

After 3 other BMW workshops couldn't fix the problem with my M3. SouthernBM sorted it. Excellent to deal with, great communication and customer service.
