This is a Mahle OE Piston Ring set, part number 3150219, designed for an 88.0mm bore. These rings are a standard tension, moly-coated set, often referred to as the HV385 series. They are built to drop right into your existing piston grooves without modification, making them a straightforward replacement for worn-out rings.

Moly-coated rings like these are known for their durability and ability to reduce friction, which can lead to improved engine performance and longevity. The specific dimensions are 1.0mm for the top ring, 1.2mm for the second ring, and 2.8mm for the oil control ring. This combination is a popular choice for many engine rebuilds where a reliable, well-built replacement is needed.
