Fits 2004+ Subaru WRX STI models with a 99.50mm standard bore size.

Manley Performance piston rings are engineered to provide a high-strength, reliable seal for high-performance Subaru EJ-series builds. This specific set features a 1.2mm ring thickness and a double-tabbed design, which prevents ring rotation and maintains proper orientation under the extreme cylinder pressures common in turbocharged engines. Whether you are performing a factory-spec refresh or a high-horsepower forced induction build, these rings offer the durability and oil control required for demanding applications.

  • Designed for 99.50mm standard bore blocks
  • 1.2mm ring thickness for precise cylinder wall sealing
  • Double-tabbed configuration for improved ring stability and index retention
  • Includes Napier-style second rings for superior oil scraping and control
  • Ductile iron construction with plasma-moly inlay for long-term wear resistance
  • Complete set of four ring packs for a full engine assembly
