**** DOES NOT INCLUDE HARDWARE ******

The S55 engine is no stranger to oil cooling problems, that’s why we recommend installing the Mosselman Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The Mosselman 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 Mosselman 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 recommended to install the thermostat, especially for cars that are tuned.

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.

Great fit and quality

Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.

Wanting to correct my previous review (I reviewed the incorrect item). This product fit perfectly in my vehicle- my apologies for the first review; perhaps Amazon or the vendor can replace the first review with this one. I am very pleased with this item.
