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.
- 0.50 mm oversize up to 100.47 mm, with a 9.2:1 standard compression ratio.
- Includes piston (individually wrapped), OEM-quality rings (boxed separately), wrist pin, and circlips.

Great, comfortable jeans.
Special Size: Low Stretch, Size: 34W x 30L, Color: Dark Midnight Wash
Great jeans! They're relaxed, but not loose or super baggy, so they still look great. I got the dark wash and you can wear them as dressy jeans or just casual out and about. I have bigger thighs and the 34x30 fits perfectly with room still to spare and not constricting at all. Whether it's walking around a lot, or sitting down for hours, it's very comfortable.
We'll see how long they last but I washed them once already and are holding up.
The length is good as well. When I don't have shoes I probably need a belt or could've ordered 29 length, but they're fine when I have shoes on. They don't slip down at all.
Especially for the price compared to Levi's or others that cost 40, 50, or even $60 this is a great deal.

If you’re on the fence read this
Special Size: Low Stretch, Size: 40W x 30L, Color: Iced Light Wash, Special Size: Low Stretch, Size: 40W x 30L, Color: Iced Light Wash
In all honesty, I was skeptical about ordering jeans from Amazon. I’ve always bought my jeans in stores, but I figured I’d give it a shot. I ordered these jeans for an upcoming outdoor wedding because I wanted something lighter and thinner. They showed up today, and I threw them on. They fit great, feel good and comfortable, and they don’t look cheap. I’ll mainly be using these for outings, so I can’t really attest to the durability as far as working in them, but I’d still suggest them. For reference, I’m 5’8” and 230 lbs with a husky build—kind of fit, kind of fat.

A Great Buy - But Might Be Too Long
Special Size: Low Stretch, Size: 34W x 32L, Color: Dark Midnight Wash
These jeans are an excellent buy! I have only bought Eddie Bauer jeans for the last 25 years, but this time I couldn't find my size in the correct style. I prefer classic/relaxed in dark blue. I don't like the "pre-washed" or worn look. The Dark Midnight Wash was exactly what I wanted - new jeans. The waist measurement was perfect. Unfortunately, the 32 length was waaay too long. (All the Eddie Bauers were 34x32). So I just did an exchange for a 34x30, which should be good. Eventhough the length was too long, I'm still giving 5 stars. Different manufacturers cut sizes differently. It is what it is. And the return process was EZ and the replacement size was in stock. Seriously, there is really no quality difference between these Amazon Essential jeans and my old $60 E.B.s No one sees the label anyway!
