MMR Performance Oil Cooler for BMW E90 E92 E93 S65 2006-2013

The MMR Performance oil cooler for the BMW M3 E9x is essential for any M3 seeing intensive use, especially those with high power levels or operating in extreme climates. Increased oil temperature means only one thing: a reduction in the engine's ability to remain properly lubricated.

Under demanding driving conditions, the stock oil cooler is easily overwhelmed. Failures begin to occur when the oil cannot dissipate built-up heat quickly enough, causing it to become thinner and degrade, thereby losing its lubricating properties.

The MMR oil cooler kit solves this problem: by adding an additional oil cooler, positioned directly in the airflow at the front of the vehicle, oil temperature is reduced by 15-20 degrees Celsius (depending, of course, on vehicle usage, ambient temperature, and engine setup). The core is 77 cm wide and 6.5 cm deep.
The MMR Performance oil cooler for the BMW E9x M3 installs in the same location as the factory cooler, making it compatible with any modification where the original cooler still fits.

Whether you have a supercharger or are simply looking to significantly improve your M3's reliability with superior oil cooling, this cooler will help keep oil temperatures in check, whether in demanding track conditions or in traffic.

Compatibility Note

For vehicles manufactured before or around March 2008, you may need to upgrade your oil lines. BMW replaced the oil lines on early models, and they are physically different. The MMR oil cooler is designed for vehicles with the later spec oil lines. These oil lines are available directly from your local BMW dealer.
