A tool with a pair of longitudinally translatable components, includes a base with a lip to engage the underside of a boot covering a spark plug of an internal combustion engine. The other component, a slideable tongue, engages the engine head to provide a controlled reaction force against the underside of the boot to force it off the spark plug. The base of the tool may be fitted against the boot for aligning the tool to direct the reaction force in a direction substantially parallel to the longitudinal axis of the spark plug. The tool is activated after alignment by manually compressing a handle connected to the tongue to move toward a finger grip rigidly secured to the base. The tongue preferably is connected to the handle by an actuating rod guided by a sleeve mounted on the base.
