    MAHLE Original® PC479 Fire-Power™ piston ring sets are engineered to withstand the punishment of today’s high powered nitrous oxide injected, turbocharged and supercharged race applications. PC479 compression rings will provide superior ring durability, stable radial tension, superior combustion sealing and oil control, while protecting the cylinder walls. All these benefits will net additional horsepower while extending engine life. MAHLE Original PC479 Fire-Power™ rings can be purchased in boxed engine sets as well as open stock to meet your performance requirements.

  • Mahle Original performance piston rings sets are the most technically advanced and rigorously tested than any other piston ring manufacture. Current racing engines demand piston rings to operate at higher operating rpm, higher compression ratio, and higher temperatures from race to race and remain dependable. These factors require rings that are stronger, lighter, seals better, and resist wear under extreme conditions.

    Features
  • Recommended for street, racing, or marine applications
  • Barrel faced top ring offers instant break-in and maintains contact with the cylinder wall as the piston rocks slightly at TDC and BDC.
  • Napier THG (hook groove) second compression ring provides superior oil control by scraping cylinder walls of oil and providing a reservoir on each down stroke.
  • CP-20 oil control ring, named by its 20 degree ear angle, and exclusive feature that provides the absolute best cylinder wall seal.
  • Available in different compression ring materials consisting of cast iron, ductile iron, gas nitride stainless steel, steel alloy.
