Engine Piston Ring Set 41564.030

The Mahle Original 41564.030 is a premium piston ring set designed for specific L4 engines. These rings are installer-friendly and pre-lapped for immediate seating, virtually eliminating break-in time.

Constructed with optimized ring materials and coatings, these sets reduce friction, minimize oil consumption, and extend engine life. The compression rings feature a barrel-faced contact area for efficient compression and a CNC-controlled gap chamfer to reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining enhances contact. The CP-20 oil ring assemblies include a 20-degree ear angle for optimal side seal against the cylinder wall, and a special chemical polish on the expander aids oil drain back.
