PISTON RING SET 4 CYL STD (Toyota TY00591-17859-81)

TY00591-17859-81: A worn piston ring set can allow combustion gases to escape past the piston, reducing cylinder compression. This aftermarket replacement part references Toyota catalog number TY00591-17859-81. The set includes rings that seal the gap between the piston and cylinder wall during operation. A common failure consequence is increased oil consumption as the rings lose their sealing ability. The part ships at approximately 0.4 pounds.
