Product Details

The MAHLE 42112CP.020 is a premium-grade piston ring set engineered for engine rebuilds requiring a +0.020" (0.50mm) oversize bore. Built to MAHLE's exacting OE-level standards, this set delivers reliable compression sealing, reduced blow-by, and effective oil control for a restored-to-factory engine performance.

Key Features:

  • Plasma-Moly Upper Compression Ring: Cast iron construction with a plasma-moly facing for superior wear resistance and fast, efficient seating against the cylinder wall
  • Pre-Lapped Rings: Factory pre-lapping virtually eliminates traditional break-in time — rings seat immediately upon startup
  • Barrel-Faced Compression Ring Contact Area: Promotes more efficient compression and reduces cylinder wall friction
  • CNC-Controlled Gap Chamfer: Precision-machined gap chamfer optimizes compression retention and minimizes blow-by
  • Reverse-Twist Intermediate Ring: Taper-race machined second ring with reverse twist design enhances groove side sealing and cylinder wall contact
  • CP-20 Oil Ring Assembly: Features an exclusive 20-degree ear angle for maximum side seal against the cylinder wall, plus a chemically polished expander for enhanced oil drain-back
  • +0.020" Oversize: Designed specifically for bored or worn cylinders requiring a 0.020" over-standard bore size
  • Optimized Ring Tension: Ring tension is balanced to reduce friction while maintaining long-term sealing performance

MAHLE is a globally recognized OE supplier and aftermarket leader, producing piston rings to the same specifications used in original equipment manufacturing. The 42112CP.020 ring set is an ideal choice for professional engine builders and performance rebuilders seeking a premium, installer-friendly solution that meets or exceeds factory compression and oil control standards.
