How to change spark plugs
Those are as easy as they come these days.
Mark each spark plug wire with a piece of tape with the cylinder # written on it, so as not to mix up the wires.
Remove each spark plug wire by firmly grasping the wire by the boot (do not pull on the wire) and twist it back and forth a few times while pulling slowly. It should pop off without a great deal of effort. If it is seized and it breaks, you will have to replace the wire, or at the very least replace the terminals (if you can get some).
Use an air hose and blow around the base of each spark plug to dislodge any loose dirt that could fall into the cylinders (not absolutely necessary, but a good idea).
Remove each spark plug with a spark plug socket and extension and ratchet (I forget which size socket, it's either 5/8 or 13/16).
Check the gaps of each new spark plug (typically around 0.035 in).
re-install each new spark plug by hand (do not cross-thread them) and once you have ensured that the plug is threaded in properly, tighten the plug until it seats, and then tighten an additional 1/16 of a turn. Repeat this for the remaining plugs.
Re-install wires to the corresponding spark plugs.
