Mahle Rings Ductile Plasma Moly Engine Set 1.5 1.5 3.0MM Std Tension Oil Ring 4.130in Moly Ring Set

This set includes ductile plasma moly piston rings for a standard tension oil ring, with dimensions of 1.5mm for the top and second rings and 3.0mm for the oil ring. The bore size is 4.130 inches. These rings are a direct replacement for your engine's original piston rings, designed to maintain proper sealing between the piston and cylinder wall. This is crucial for efficient combustion, oil control, and overall engine performance.

Mahle OE uses ductile iron for the top ring and plasma-moly coating on the second ring, which helps reduce friction and wear. This combination offers good durability and helps ensure a solid seal under normal operating conditions. Proper ring seal is essential for preventing blow-by, which can reduce power and increase oil consumption. This set is intended for standard tension applications, meaning it's designed to work with your engine's original piston and cylinder specifications.
