It's really easy and basically foolproof if you will use about an 8" straight section of rubber heater hose or vacuum line that will fit over the tip/cap and snuggly onto the ceramic insulator of your new spark plug. You can then thread them in by hand and pull the hose off once the plugs are initially seated. Use the socket-extension-ratchet only to take the old plugs out and snug up the new ones you install.
