**STOCK DUE OCTOBER, 24**
Control the oil temperature on your BMW N54 or N55 engine by fitting the MMR Performance Low Oil Temperature Thermostat. By maintaining your oil temps between 90c - 110c, this is an essential modification for all high power or hard-driven cars, especially those used on track. Only fits models from 2008 onwards.
Adding power to your engine generates more heat to disperse. Equally, hard driving, particularly in a warmer climate also pushes temperatures higher than optimum. Significantly increased oil temperatures means only one thing: a decrease in the ability for your engine to stay properly lubricated.
In order to properly control the oil temperature on your N54 or N55 engine, fitting the MMR low oil temp thermostat is one of the best ways to allow you to maintain your oil temps between 90c - 110c. It's a much cheaper option than the addition of an expensive oil cooler system!
Machined from aircraft grade T-6061 aluminium before being anodised in the proprietary Dark Anthracite MMR finish for durability.
Installation of the MMR Low Oil Temperature Thermostat is relatively easy into the OE oil thermostat housing found on the N54 and N55 engines. Please note: only suitable for models from 2008 onwards.
This upgrade is a highly recommended, affordable modification for any hard-driven cars used on track, or that have an increased power / torque output and are therefore generating more heat than OE car would do.
