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

The BMW N55 and S55 engines are no strangers to oil cooling problems, that’s why we recommend installing the Mosselman Oil Thermostat. Instead of opening at 105°C (220°F), the Mosselman Oil Thermostat opens at 85°C (185°F) which results in an operational oil temperature 20°C (68°F) lower than OEM. *Exact temperatures can differ slightly depending on the engine type.

Installing the Mosselman Oil Thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. A highly recommended upgrade for the N55, and S55 engines, especially when they’re 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.

Finish the look of your Mosselman Oil Thermostat with the optional Titanium Bolt Installation Set. GR5 Titanium, M8x25.

I as well as my 6 year old use and like
Size: 1.35 Fl Oz (Pack of 1), Style: Cicaplast Baume B5 Balm
This balm has been amazing for dry and irritated skin. I started using it on rough patches around my nose and cheeks, and it helped calm everything down quickly. The texture is thick but it absorbs better than I expected. A little goes a long way, so the tube lasts quite a while. I also like that it does not have a strong fragrance that irritates sensitive skin. It works well under makeup and overnight as a treatment. I will definitely keep repurchasing this because it has become a staple in my skincare routine.

52, Post-Menopausal Dry Skin — This Is My Barrier Emergency Product
Size: 1.35 Fl Oz (Pack of 1), Style: Cicaplast Baume B5 Balm, Size: 1.35 Fl Oz (Pack of 1), Style: Cicaplast Baume B5 Balm
I’m 52 with post-menopausal, mature dry skin, and this is not something I use casually or every day — it’s what I reach for when my skin barrier is compromised and needs real help. When my skin is irritated, over-exfoliated, reacting to actives, or feeling tight and inflamed, I don’t want glow or anti-aging claims. I want calm, protection, and repair. This balm delivers exactly that. The texture is rich and occlusive, but not greasy or suffocating. It melts into the skin and immediately takes the edge off irritation — that tight, uncomfortable feeling just stops. Within minutes, redness looks calmer, dryness is softened, and my skin feels protected rather than coated. It creates a breathable barrier that actually stays put overnight, which is especially important on mature skin that loses moisture quickly. What I appreciate most is that this works with my existing routine instead of competing with it. I use growth factors, peptides, and treatment serums regularly, and when my skin needs a reset, this seals everything in without stinging or interfering. I’ve used it after retinoids, during periods of sensitivity, and when my skin simply feels fragile — and it consistently helps restore balance. That said, if you have very oily skin or are looking for a lightweight daytime moisturizer or a dewy “glass skin” finish, this probably isn’t the product for you. This is a true treatment balm, designed for barrier repair rather than cosmetic glow. This is not a glow cream, a makeup primer, or a lightweight moisturizer, and that’s exactly why it’s so effective. It’s a true barrier balm. On my dry, post-menopausal skin, it reduces flaking, minimizes irritation, and helps my skin recover faster so I can get back to my normal routine without setbacks. With so many skincare products making big promises, this one quietly does its job — and does it extremely well. If you have mature, dry, or reactive skin and need something reliable for barrier repair, this earns its place. It’s not exciting, it’s not trendy — it’s just very, very effective.

Lightweight SPF that layers well under makeup
Size: 5 Fl Oz (Pack of 1)
This sunscreen feels much lighter than many high-SPF formulas I’ve tried and blends into the skin without leaving a heavy white cast. The texture spreads easily and gives a hydrated finish without feeling greasy, which makes it comfortable for everyday wear on both the face and body. I also liked that it layered well under makeup without pilling. I used this during long outdoor days and it held up well while still feeling comfortable on the skin. The SPF 60 protection is reassuring, especially for travel, beach days, festivals, or daily sun exposure. Overall, this is a reliable sunscreen option if you want strong protection with a more wearable, skincare-like texture.

A Must-Have for Sensitive Skin
Size: 5 Fl Oz (Pack of 1)
recently tried La Roche-Posay sunscreen and I’m really impressed! 🌞 The texture is lightweight, non-greasy, and absorbs quickly without leaving a white cast, which is a big plus for daily wear. It feels gentle on my skin and doesn’t clog pores, making it perfect for sensitive or acne-prone skin. I also love that it provides strong, broad-spectrum protection while still feeling breathable. Overall, it’s become my go-to sunscreen—I actually enjoy applying it every morning because it feels more like skincare than sunscreen. Definitely worth it! I would be honored if you would consider me to receive a PR package. I’d love the opportunity to try more of your products and create authentic content that highlights the benefits of La Roche-Posay skincare. Thank you so much for your time and consideration! Warm regards, Andrea Mohanlall
