The Mahle OE chrome ring set is a piston ring kit sized for a 4.2500 in bore with 3mm edge width and CP20 low-tension chrome rings. Intended to seal the piston-to-cylinder interface, these rings provide the functional benefits expected from an OE-style replacement set. The set suits engine rebuilds where a chrome, low-tension ring specification is required and complements other matched piston and cylinder components.
