Manley 46920DT-1 Piston Ring Set 92mm Bore File Fit Subaru EJ205 EJ257

The Manley 46920DT-1 is a high-performance piston ring set designed specifically for Subaru EJ205 WRX and EJ257 WRX STI engines with a 92.0mm bore. This file-fit ring set is engineered to deliver superior sealing, minimal blowby, and increased horsepower while maintaining cooler, cleaner oil for extended engine life.

Key Features:

• 92.0mm bore diameter with file-fit design for precise end gap adjustment
• Ring dimensions: 1.2mm x 1.2mm x 2.8mm configuration
• Ductile iron plasma moly top ring for exceptional wear resistance
• Conventional reverse twist cast iron second ring
• 3-piece standard tension oil ring with double-tabbed oil rails
• Sold as a single piston ring set (for one piston)

Manley piston rings are purpose-built to work seamlessly with Manley pistons and feature advanced materials and manufacturing processes to ensure optimal ring groove to skirt squareness. The plasma moly coating on the top ring provides superior durability in high-performance and forced induction applications. File-fit design allows engine builders to precisely gap the rings for their specific build requirements.

Note: This ring set is designed for use with Manley pistons only. Sold individually per piston, not as a complete engine set.
