MAHLE 3150190.005 Piston Ring Set Bore Plasma Moly - 4.187

The MAHLE 3150190.005 is a premium piston ring set engineered for high-performance engine builds requiring precise 4.187-inch bore sizing. This complete ring set features advanced materials and coatings designed to maximize sealing efficiency, reduce friction, and extend engine life.

Key Specifications:

• Bore Size: 4.187 inches
• Top Ring: .017-inch Dykes-style (gap-type) ring for superior blow-by control
• Second Ring: 1/16-inch plasma moly-coated compression ring
• Oil Ring: 3/16-inch high-tension ductile iron construction
• Plasma moly coating provides exceptional wear resistance and faster break-in
• High-tension design ensures positive ring seating and optimal cylinder sealing

MAHLE ring sets are manufactured to OE specifications and exceed industry standards for dimensional accuracy and durability. The plasma moly coating on the compression ring reduces friction while providing superior scuff resistance during critical break-in periods. The ductile iron oil ring maintains consistent tension for effective oil control throughout the engine's service life. Ideal for performance rebuilds, racing applications, and demanding duty cycles where premium ring performance is essential.
