The Mahle OE chrome ring set is a precision replacement for engines with a 4.1250 in bore and 3mm edge width, featuring a CP20 oil ring and low-tension chrome rings for controlled sealing. It’s intended as an OE-style fitment option to restore piston-to-cylinder sealing and ring function where chrome ring specifications are required.
