MAHLE S50664CP Engine Piston Ring Set

The MAHLE S50664CP is a premium quality piston ring set engineered for precision engine rebuilds and performance applications. MAHLE Original piston ring sets are designed to be installer-friendly and are pre-lapped to seat immediately, virtually eliminating break-in time.

Advanced Engineering Features:

• Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application
• Compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blowby
• Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact
• CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drainback

MAHLE piston rings are the most technically advanced piston rings in the industry, driven by OE requirements; reducing friction and ring mass while minimizing engine oil consumption, and providing longer service life. MAHLE is one of the largest OE piston ring manufacturers in the world and leads the industry for the latest piston ring technology.

Important: Always verify ring specifications including bore size, ring thickness, and groove dimensions match your pistons before installation. Proper ring gap measurement and installation procedures are essential for optimal performance and engine longevity.
