My spark plug sockets had problems -- either the little rubber boot that was up inside it would pull off on the plug, the plug would fall out of the socket (because the socket was old, old, old), the socket was too fat to get in to the limited area of the head, etc. So I decided to spring for a fancy-schmancy spark plug socket called "Lockit Socket" that actually holds the plug securely in the socket with a little wire gizmo. It actually works, so I thought I would take a shot of it and post it here.
