Mahle Rings 4.0000 Bore Dia 3/16in Edge Width CP20 Oil Ring Std Tension Chrome Ring Set

Mahle is a well-known name in engine components, often supplying parts directly to automakers. This piston ring set, part number 3030115, is designed for a 4.0000 inch bore and features standard tension chrome oil rings. The 3/16 inch edge width is a common specification for many engine rebuilds.

These rings are built to OE specifications, meaning they are made to fit and function just like the original parts. The chrome plating on the oil ring helps improve durability and wear resistance, which is important for maintaining a good seal between the piston and cylinder wall. Proper sealing is key to preventing oil from entering the combustion chamber and ensuring efficient engine performance.
