Rogue Engineering BMW E46 M3 RACE Oil Cooler

While the Rogue Engineering/CSF 8032 oil cooler continues to have great success, Rogue Engineering realized they needed more. Based on their endurance racing, they saw that oil temps over the course of 8 hours or more needed a different strategy for cooling. Some E46 M3s are fine with a smaller cooler for shorter races, running long stints in endurance racing is different.

The basic idea was to add more volume in the relatively small space available for the factory cooler. After a few prototypes, the design was finalized, and sent over to CSF. From the conceptual drawings, CSF was able to create this monster cooler. The result was a cooler with 445 cu. inches of volumetric size. That is more than FOUR times the size of the factory OEM cooler! Additional features include 1/8 NPT threaded ports to allow for monitoring oil temps leaving and returning back to the engine! Get the true delta of what the cooler is doing for your E46 M3!

Fitting this cooler also means creating the appropriate lines to replace the factory oil lines, since they cannot be used. While an AN10 adapter for the OEM oil filter housing is included, it is the responsibility of the buyer to make the lines from the oil filter housing to the oil cooler.

Note that this item is designed to be used for race-only, track-only vehicles. Since this is a race-only part, Rogue Engineering assumes NO responsibility to fitment with OE/OEM parts used on street driven vehicles. Returns are NOT accepted for fitment issues such as underbelly supercharger cooling tanks, aftermarket skid plates or additional intake/cooling ducting that may hang under the vehicle. If you have any of the aforementioned items, DO NOT purchase this item.

Since this is a race part, it is up to the customer to produce their own AN10 lines from the oil filter housing to the cooler.
