MAHLE 3150164.015 Plasma Moly Piston Ring Set Bore - 4.135

The MAHLE 3150164.015 is a premium piston ring set engineered for high-performance engine builds requiring a 4.135-inch bore diameter. This advanced ring set features plasma-moly coating technology combined with ductile iron construction for exceptional durability and wear resistance in demanding applications.

Key Specifications:

• Bore Size: 4.135 inches
• Ring Width: .043 inch (1.09mm)
• Oil Ring: 3.00mm
• Plasma moly face coating for superior wear resistance
• Ductile iron construction for enhanced strength
• Low tension design reduces friction and increases horsepower
• Reduced radial wall thickness for improved ring seal

MAHLE's plasma-moly coating process creates an exceptionally hard, low-friction surface that accelerates break-in and provides long-term durability. The low-tension design minimizes friction losses while maintaining excellent cylinder sealing, making this ring set ideal for performance street engines, racing applications, and engine rebuilds where maximum efficiency is critical. Each set includes compression rings and oil control rings engineered to MAHLE's exacting OE specifications.
