111 107 361 B : Piston ring for classic vehicle

The piston ring is an essential engine component: it ensures the seal between the piston and the cylinder liner, contributes to compression and participates in heat evacuation towards the cylinder wall. In the context of restoration or thorough maintenance of a classic vehicle, its replacement is often necessary during an engine overhaul, particularly in the event of excessive wear, abnormal oil consumption or loss of compression. This new part allows the engine to regain its original characteristics and ensure reliable operation over time.
