Mahle Rings NISSAN MOT/ENG 1.8L J-18 DATSUN 3.1693in 80.50mm DIAM. 4 CYL .059 .078 Moly Ring Set

These Mahle OE piston rings are built to precise 80.50mm (3.1693 inch) diameter specifications for 1.8L 4-cylinder Nissan and Datsun engines. They feature a moly coating, which helps reduce friction and wear on the cylinder walls and the rings themselves, contributing to a longer service life for your engine rebuild. Mahle focuses on meeting original equipment requirements, aiming to minimize oil consumption and improve overall engine efficiency.

When you're rebuilding an engine, the piston rings are a critical component. They seal the combustion chamber, transfer heat from the piston to the cylinder wall, and regulate oil consumption. Mahle's approach is to develop rings that are technically advanced, focusing on reducing friction and ring mass. This attention to detail helps ensure your engine runs smoothly and efficiently after the rebuild.
