Mahle Rings Toyota 1.3L / 1.5L 2NZFE / 1NZFE 2000-2005 Echo Prius GNS Top Ring Plain Ring Set

MAHLE(R) piston rings are technically advanced, driven by OE requirements for reduced friction, minimized oil consumption, and extended service life. These piston rings feature a barrel-faced contact area for efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies provide a 20-degree ear angle for excellent side seal against the cylinder wall, and a special chemical polish on the oil ring expander enhances oil drain back. Mahle Original piston ring sets offer quality and ease of installation, making them a preferred choice for engine builders.
