Namura provides high-quality piston options to suit a wide range of applications, including direct OEM replacements, high-compression variants, and multiple oversizes. B (0.01 mm) and C (0.02 mm) oversizes are also available, helping to extend the service life of expensive plated cylinders. Select applications are supported with big-bore piston kits. With the addition of MOS2 coating and hard anodising, Namura delivers improved performance and durability, without the premium price.
Features:
- MOS2 (Teflon/Molybdenum) Coated Skirts: Applied using a rolled-on process for a bond up to 10 times stronger than typical spray coatings. Improves heat transfer, reduces friction, and helps prevent cold seizures.
- Machined Smooth Heads: Reflect combustion heat and minimise carbon build-up, protecting the piston crown. Testing indicates potential gains of up to 6% in horsepower and fuel efficiency.
- Anodised Domes: Enhance heat resistance and durability, with up to 75% greater strength compared to non-anodised pistons.
- Hypereutectic Casting Process: Increases silicon content to reduce expansion, improve wear resistance, and withstand higher cylinder temperatures.

Glass skin in a bottle
I read a review here saying this product was glass skin in a bottle before purchasing myself, and to be fair, I didn’t get it because of that particular effect, but the way my skin has changed since I started using it is just amazing. I’ve been using this for several months now along with the toner and moisturizer from the same line. This is hydrating, leaves a beautiful glow on the skin, wears great under makeup, and I’ve noticed more and more people commenting on how nice and healthy my skin looks since I started using it. I am currently going through a hormonal acne flare up, and this helps my skin feel calm and does not break me out at all.

Hydrating and NOT Sticky!!
As someone who has VERY dry and sensitive skin, I love this product. It gives me an extra layer of protection during the cold and windy days, so I don’t have to worry about my skin burning or peeling the next day. It’s pretty lightweight, and really only feels like you are putting on water almost. It gives your skin a subtle glow too which is nice, and has no scent (which is perfect for sensitivity). It works super well and makes your skin looks plump. The only reason I’m docking a star is because a few times I’ve used this I have had issues with my makeup (especially around my eyes) separating or peeling off. I’m not sure if this is happening because of the reaction with this product and my sunscreen or what, so take that with what you will!

Great Skin Product
I’m absolutely impressed with the ANUA Rice Ceramide 7 Hydrating Barrier Serum! This fragrance-free Korean skincare serum combines the power of rice, hyaluronic acid, and niacinamide to brighten, hydrate, and strengthen my skin barrier. After using it regularly, my complexion looks noticeably more radiant and plump — that coveted glass skin glow is definitely real!
The serum is lightweight and non-comedogenic, making it perfect for daily use without clogging pores or causing irritation. It complements my routine perfectly after cleansing with the Anua Heartleaf Pore Control Cleansing Oil and using the 3-in-1 Jade Roller and Gua Sha Facial Kit to boost absorption and circulation. Together, these products have transformed my skin, reducing wrinkles, controlling pores, and keeping my skin hydrated and fresh.
If you want a gentle yet effective serum that brightens and deeply hydrates while supporting your skin’s natural barrier, this is a must-have!

High quality incredible serum
I LOVE this serum! I really feel like it hydrates my skin and it’s non greasy, easy to apply and no smells. For the price it us really good value for the money. Easily comparable to expensive products. It’s really easy for my skin to absorb and it’s lightweight.

Great for dry skin
Looovvveee this stuff. At first it feels a little sticky but once your skin absorbs it, it feels so hydrated. I was worried about using this because i have dry and sensitive skin but if anything it made my skin calm down. I haven’t broken out and i’ve been using it for a while, makes my skin so glowy too.
