Description
Piston rings are critical to engine sealing, compression, and oil control—neglecting quality rings leads to blow-by, power loss, and accelerated wear. The 4005MS-15 delivers plasma-moly coated reliability across all eight cylinders, maintaining consistent ring tension and bore contact under demanding conditions. For high-performance and rebuilt engines, file-fit rings demand precision installation but reward you with superior ring-to-bore conformity and extended service life.
