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.

ITS SOOOO FLUFFY!!
Color: Orange
Ooouuu she’s so fluffy!!!!!! Omg, I’m in love. The color looks exactly as pictured. The gear shift cover was way too small for my RAV4 but it’s okay, it kind of interfered with the button to move the gear. Also, if you need to see the info on the dash, be aware that the steering wheel cover blocks it for the most part. I’m not bothered by it but it’s something to make note of for those who might be.

Warm and soft!!
Color: Orange, Color: Orange
So funky and cute! Matches my inferno orange car! I really only wanted the steering wheel cover & have no need for the other covers because they don’t fit on my shifter, or my parking break. Besides, it gets kind of dirty on the console. Keeping gloves in the car so it doesn’t end up dirty from my hands this winter:) It does make it a bit hard to see the ignition and some of the gauges as it is so fluffy, but it’s so funny, I don’t care! Lol

Came vacuum sealed. No smell. I ABSOLUTELY LOVE how fluffy it is!!! The color is a perfect match to my car. I don’t have an emergency break lever so I couldn’t use that. Overall 10 out of 10 rt now!
