Namura piston kits come with the piston individually wrapped; a set of OEM quality rings packed in their own box, a wrist pin, and circlips.
- MOS2 (Teflon/Molybdenum) Coated Skirts: A rolled-on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction, and helping to eliminate cold seizures.
- Machined Smooth Heads: Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%.
- Anodized Domes: Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons.
- Hypereutectic Casting Process: Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.
Namura gaskets are manufactured to OE-specs, which means no trimming or fitment issues. Our materials are explicitly selected for their temperature, oil, fuel, and coolant-resistant qualities as well as tested using ASTM standards. Each design is evaluated against rigid quality-control standards to ensure each set meets or exceeds OE performance.

My AmazonFinds/ SPF 50 Sunscreen
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50, Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
I’ve been using this Banana Boat Sport SPF 50 sunscreen and I really like it. It goes on smoothly and absorbs quickly without feeling too greasy or heavy on the skin. I also like that it’s water and sweat resistant, which makes it perfect for outdoor activities or beach days.
It provides strong sun protection and I feel confident using it when I’m out in the sun for long periods. The scent is light and not overpowering. Overall, it’s a reliable sunscreen that I would definitely buy again.

Very good sunscreen, advice from a pale-skinned person
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
I'm Scottish by descent, and so is my skin. This stuff works well, is pleasant, not greasy and seems to hang on despite kiteboarding, surfing, cycling, whatever. Pleasant smell, good dispenser.

Good product, the pump bottle could be better
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50, Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This is a usual product for me, I like and trust it. It has little smell, spreads on easily and can be washed off without too much trouble. The pump is nice while it works but I take away one star because it leaves about 20% of the product in the bottom of the bottle when the "cone of depression" gets lower than the bottom of the tube that brings the product up. After the pump can no longer effectively pump the product up, I cut the top of the bottle off and dip the rest out with my fingers. I'm not sure what they can do to make it work better but it's inconvenient as it is.

Excellent protection for workouts and hot days! ☀️🏃♂️
Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This sunscreen is fantastic for daily use and outdoor activities. The SPF 50 protection is highly effective; I’ve used it under intense sunlight and haven't gotten burned at all. What I love the most is that it actually resists sweat and doesn't run into your eyes when you are working out. It doesn't leave an overly greasy feel, and the 8oz size lasts a long time. It is a reliable product that is always in my bag. 100% recommended purchase!

Very helpful
Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This sunscreen is a fantastic value, especially since I managed to grab it while it was on sale. It applies smoothly without feeling overly greasy and provides solid protection for outdoor activities. It is definitely worth picking up if you can find a good deal on it, as it does exactly what it is supposed to do. I will be keeping an eye out for another sale so I can stock up for the rest of the summer.
