MAHLE 4315ML File Fit Piston Ring Set Bore - 4.310 1/16 1/16 3/16

The MAHLE 4315ML is a high-performance file-fit piston ring set designed for 4.310" bore engines with a +.005" oversize tolerance. This low-tension ring set features a 1/16", 1/16", 3/16" configuration engineered to reduce friction and maximize horsepower output.

Ring Configuration:

• Top ring: Ductile iron with plasma moly coating and barrel face design for superior wear resistance and sealing
• Second ring: Cast iron reverse twist configuration for optimal oil control and cylinder wall sealing
• Oil ring: 3-piece low tension design for reduced friction and improved oil management

Key Features:

• File-fit design allows precise end gap customization for your specific application
• Low tension construction minimizes friction losses for measurable horsepower gains
• Ultra-flat ring flanks maximize ring-to-piston groove sealing
• Plasma moly top ring coating provides excellent scuff resistance during break-in
• Computer-optimized ring geometry developed through advanced simulation tools

MAHLE's advanced piston ring technology has been proven on both the dyno and the track, delivering free horsepower through friction reduction while maintaining excellent sealing characteristics. Ideal for performance rebuilds and racing applications where every horsepower counts.
