MOSSELMAN OIL THERMOSTAT  F- Series BMW

 

This Kit Includes the Gasket, O Rings, and Titanium Bolts needed for installation. 

The N54, N55 and S55 engines are no strangers to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius, depending on the car model.

Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is highly recommended to install the thermostat, especially for cars that are tuned.

THE NEXT LEVEL OF TEMPERATURE CONTROL

A highly recommended upgrade for N54, N55 and S55 engines.

The Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at our own facility. It is equipped with a real thermostat, not an always open solution. The oil will still reach the operating temperature at the same time as a stock thermostat.

Additionally to the thermostat we have oil cooler kits for the 1-Series E8x and the 3-Series E9x. We advise the Oil Cooler Kit for cars that use the full performance of the car during track use. The kits are available as single or twin cooler kits. The single cooler kit replaces the OEM cooler on the right side of the car, the twin kit will add an extra cooler on the left side of the car.

BM3 Vehicle Compatibility and Unlock Status Check Procedure

Connect to your vehicle, (you need to get an OBD2 Ethernet cable and an MFI certified adapter cable if applicable or a WiFi adapter) start the OBD agent (you can get it here: https://www.bootmod3.net/downloads/ or our APP) and before you’re about to log in on https://www.bootmod3.net , click on the ‘check support' button on the right-hand side. If using our app, login, click on vehicle and you should have this information (if locked or unlocked) already displayed on that page.

Message written in bold letters under your software ID's will let you know if we have support for your engine type. It will also tell you if you need a bench unlock or not, and what type of an unlock is needed if you do need one.

If the message states that your DME requires a bench unlock before flash-tuning your vehicle, you will need to reach out to one of our authorized dealers and inquire about a bench unlock. The listing for all of our authorized dealers can be found in the link attached below.
