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.

Nice fresh and clean.
Scent: Lemon
I use this for general cleaning, smells fresh, and picks up dirt. I also like it for my acrylic bath tub to remove soap build up no scratching.

When you need some real cleaning power.
Scent: Lemon
Be careful of this stuff. It is very powerful. But wow, does it clean. It can cool rust off of many items. Smell is overpowering. Price is terrible but what else is new? It does not foam unless it comes into contact with something reactive. I put mine in a squeeze bottle for better application.
