This high-quality piston kit offers an excellent alternative to original equipment manufacturer (OEM) parts, providing significant cost savings compared to replacing the entire cylinder. ### Advanced Technologies for Optimal Performance Namura utilizes advanced technologies to ensure top-tier quality and performance. The piston skirt features a MOS2 (Teflon/Molybdenum) coating, which enhances heat transfer, reduces friction, and prevents cold seizures. The smooth, machined piston head reflects combustion heat and minimizes carbon buildup, potentially increasing horsepower and fuel economy by up to 6%. The anodized piston dome enhances heat resistance and durability, while the hypereutectic casting process ensures higher silicon content, reduced thermal expansion, and added wear resistance. ### Complete Kit, Ready for Installation The Namura NA-50083 piston kit includes an individually wrapped piston, a set of OEM-quality rings packed separately, a wrist pin, and circlips. The +2mm oversize refers to the difference between the nominal piston diameter and the cylinder bore it operates in. ### Benefits of Choosing Namura: * **Increased Engine Performance and Reliability:** Enjoy smooth and efficient engine operation thanks to Namura's advanced technologies. * **Extended Engine Life:** Reduced friction and wear contribute to a longer engine lifespan. * **Cost Savings:** Replacing the piston is a cost-effective solution compared to replacing the entire cylinder. * **Precision Engineering:** The Namura brand guarantees high quality and precision engineering.
