Rogue Engineering is proud to introduce it's high performance E46 M3 oil cooler, produced in conjunction with CSF as a technical partner.  

OEM vs. Rogue Engineering

Some will say, "Hey!  The factory already comes with it's own oil cooler!".  Yes, it does.  Unfortunately, when the E46 M3 runs around the track for only a few minutes, the oil temperatures skyrockets quickly.  Keeping the temperatures under control prevents the breakdown of the synthetic oil in the engine.  This is a MUST for anyone that drives their E46 M3 at the track or at the limit!

At (1.3)m2 surface area, the factory oil cooler struggles to keep temperatures cool on hot days and stop and go traffic.  With the Rogue Engineering/CSF designed version, surface area increases to (2.4)m2, near double.  This allows for cool, consistent temperatures in the hottest of days driven at the very limit.  Testing in our own track car showed that a preproduction sample to provide near similar results as a high dollar oil cooler currently available on the market.

The Rogue Engineering/CSF oil cooler uses a bar and plate construction (vs. tube and fin) in a top/bottom configuration.  During the development process, we considered a front/back design, but with the of the core size (being only 3") it would only increase the price of manufacturing.  Real world testing showed no noticeable performance benefit.  The cooler uses extruded end tanks means a much stronger design than simple bent aluminum sheet construction.  This is also designed to bolt to the CSF Performance Radiator or OEM unit in addition to using the factory oil cooler lines.

Replacement OEM oil cooler o-rings are recommended with installation.  

This is designed only to fit:
  • All E46 M3
  • All E9X M3
