MAHLE 3010211B Fire-Power Piston Ring Set Bore Standard Tension - PC479 4.130 1/16

The MAHLE 3010211B Fire-Power PC479 piston ring set is engineered for high-performance applications including nitrous oxide-injected, turbocharged, and supercharged engines. This standard tension ring set features a 4.130-inch bore diameter with 1/16-inch top compression rings designed to deliver superior durability and sealing performance.

Key Features:

• PC479 compression rings provide superior ring durability and stable radial tension
• Barrel-faced top ring offers instant break-in and maintains consistent cylinder wall contact
• Napier THG (Tapered Hook Groove) second compression ring delivers superior oil control
• CP-20 oil control ring with exclusive 20-degree ear angle for optimal cylinder wall sealing
• Plain cast iron construction with phosphate coating for reduced friction
• 1/16" top ring, 1/16" second ring, 3/16" oil ring configuration

This ring set provides enhanced combustion sealing and oil control while protecting cylinder walls, resulting in additional horsepower and extended engine life. The barrel-faced design maintains contact as the piston rocks at top and bottom dead center, while the THG second ring scrapes oil and creates a reservoir on each down stroke. Contains rings for one cylinder.
