The Mahle OE chrome piston ring set is a replacement ring assembly for a 4.1700-inch bore using 3 mm low-tension CP20 oil rings. It provides sealing and oil control during engine operation, suited for rebuilds that call for chrome-ring oil control. The low-tension profile helps limit friction while maintaining oil scraping and compression sealing for engines sized to a 4.1700 in bore.
