Glow Plug Sleeve for changing glow plugs on a 2008 Ford Super Duty 6.4L diesel engine. Works great. I would not change a glow plug without one. It is a very simple cylinder with a flange, easily sketched from scratch. AA battery included in photo for scale. Other photo shows tool in place when changing a glow plug.
