A spark plug tool for installing a spark plug utilizes a flexible shaft. The flexible shaft secures to a tubular housing on one end. A handle locates on the other end of the flexible shaft. The tubular housing has internal polygonal sides formed in it for mating with polygonal sides of a spark plug. A resilient liner located in the housing grips the insulation sheath of the spark plug to retain the spark plug with the housing. The shaft can be detached from the housing after it has been used to initially tighten the spark plug. A square hole formed in the upper end of the housing will receive a conventional socket torque tool.
