Mahle Rings 4.1300in Bore CP20 Low Tension 3/16in Oil Ring Assembly Chrome Ring Set

The 4.1300-inch bore size and 3/16-inch oil ring specification are key details for this Mahle OE piston ring set. This set is designed with a low tension oil ring assembly, which can help reduce drag and improve overall engine efficiency by minimizing friction between the piston and cylinder wall. Mahle is a well-known name in engine components, and this ring set is built to meet OE specifications for a reliable fit and function.

When rebuilding an engine, selecting the right piston rings is crucial for proper sealing and performance. This set uses chrome plating on the rings, a common practice that adds durability and helps the rings seat properly against the cylinder walls. This contributes to a solid seal, preventing combustion gases from escaping past the piston and oil from entering the combustion chamber.
