Oldsmobile/Buick Repair: How to change spark plugs on a 1988 88 delta royal, swivel adapter, porcelin

Question
what do i need to get or do to change the spark plugs on my sisters 1988 88 Delta Royal Oldsmobile. We know that the spark plugs are what is causing her car to misfire, and she wants me to change them. But i am not sure what tools i might need and what to do exactly.  

Answer
Hi Jessica,
Buy the replacement plugs, get a spark plug socket that fits them, a ratchet and a couple extensions, and a flex swivel adapter if you can, so you don't put side pressure on the porcelin.

You might consider changing the wires and cap/rotor also.
