What does the '.030' in the part number mean?

The '.030' indicates that these piston rings are 0.030 inches undersize. This means they are intended for use in engine cylinders that have been bored out to a larger diameter, typically during an engine rebuild to account for wear or to increase displacement.

Are these rings suitable for a performance engine build?

Yes, Mahle OE rings are designed to meet original equipment requirements and help minimize friction and oil consumption, which are beneficial for both standard rebuilds and performance applications. Proper installation and cylinder preparation are key for optimal performance.
