PRODUCT INFORMATION

THE NEXT LEVEL OF TEMPERATURE CONTROL

The N54, N55 and S55 engines are no strangers to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat, especially for cars that are tuned. The standard oil temperature will reach around 120°C (250°F) with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85°C / 185°F) and will keep the temperature stable between 95 and 105°C (200 and 220°F), 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 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.

Installation instructions come with kit.

Suitable for F87 M2 Coupe (N55), F20 M135i Hatch, F22 M235i Coupe, F23 M235i Convertible, F30 335i Sedan, F31 335i Touring, F34 335i Gran Turismo, F32 435i Coupe, F33 435i Convertible and F36 435i Gran Coupe.

Note: You will need the N54 Oil Thermostat for the E-Series 135i and 335i with the N55 engine.

The Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at Mosselman's 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, Mosselman 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.


EXPERT'S ADVICE:

"The N55 engine is no stranger 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 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.

Note: The Oil Thermostat Installation kit prevents the Oil Thermostat from leaking and is highly recommended when installing the MSL Oil Thermostat. The kit includes 2 x O-ring for the oil hose and 1x rubber oil filter housing gasket. We advise to add it to your order."

Nice and sturdy!
Size: 300 Count
This was our first time to try the Amazon Basics Everyday Plates. I typically purchase paper plates in bulk from a big box club store. These are just as good, if not better! They are thick and sturdy, and hold up well. The price point it also better! My only negative is the design on the plate isn’t the most appealing. I think it’d be better if the design was limited to just being on the edge, and not across the entire plate.

Great Size, Strong Enough for Everyday Use, and Worth Reordering
Size: 300 Count
I reorder these regularly, and that really says the most. They’ve been consistent, practical, and a good value for what you get. They’re strong enough to handle normal meals without feeling like they’re going to give way. I’ve had no issues using them for everyday food, and they hold up well as long as you’re using them as intended. I also like the size. They’re a little over 8½ inches, which works well for most meals. If I have something heavier, I can put a plate holder underneath, and these still fit just fine. The print/design is simple, which I don’t mind at all. I’m more concerned with how they perform, and these do what I need them to do. I’ve used name-brand paper plates before, and for my everyday use, I feel like these compare very well, especially considering the price. I’ll also be honest—paper plates just make sense for me. I tend to drop things because of how my hands work, so this helps prevent broken dishes and the cleanup that comes with that. Plus, it definitely cuts down on doing dishes. Overall, these are reliable, affordable, and something I’ll continue to reorder.

Great Everyday Paper Plates for the Price
Size: 100 Count (Pack of 1)
For around six bucks, getting 100 microwave-safe paper plates like this is a really good deal. Also, they’re actually pretty good quality. They can hold a decent amount of food and they don’t get all soggy or start dripping through the bottom halfway through eating. The soak-proof part is legit. Another thing I liked is the design. The white and green looks simple but nice, and they honestly just look better than a lot of the random cheap paper plates out there. I’ve been using them pretty regularly for quick meals and throwing food in the microwave, and they’ve been really convenient. I will say, if the food is extremely hot, the bottom of the plate does warm up pretty fast since the plates are somewhat thin underneath. Sometimes using two plates instead of one helps with that. Aside from that though, they’ve been excellent. For the amount you get, the quality is genuinely solid and they’ve held up really well for everyday use. Amazon Basics definitely nailed these. 100% would recommend them.
