Here's an earlier post re changing spark plugs - the key is using a wrench with a longer handle for more leverage & taking your time. Once you have the longer wrench, slowly apply leverage and they come loose easily - make sure the socket is completely seated on the plug before trying to loosen.
I recently did mine for the first time and will pass on what I learned from experience. I hope this helps.
Parts
I used AC Delco Iridiums #91-485 $55.
I used a set of stock replacement Autolite wires for $35.
(I bought both at Advanced Auto).
Anti seize compound to put on the threads of the new plugs
Dielectric grease
Tools
5/8" Craftsman swivel socket
3 inch extension, 6 inch extension, 10 inch extension depending on location
1/2" drive Craftsman pivoting head socket wrench (21" handle) with 1/2" to 3/8" adapter
3" long piece of vacuum hose that slips over the plug insulator so you can start the threads in by hand
Mechanic gloves so you don't destroy fingers, hands, and knuckles
Helpful Hints
Change the plugs when the engine is COLD.
The rear plug on the drivers side (#7) is the hardest so get the feel of some of the easier ones before you go there.
The hardest part for me was getting the old wires off. Make sure you grab the end of the boot and yank really hard - don't worry if you destroy a wire because you have a new set.
The long handled pivoting head ratchet made the job a breeze because it gives you great control and leverage to break the plugs free & the extensions keep your hands well above the tight spots. I tried with a smaller ratchet but wasted about an hour and got frustrated as well.
Put a light coat of anti seize on the threads of the new plugs and start them in by hand as tight as you can get.
Put the socket wrench on, snug then go 1/16 of a turn.
Put some dielectric grease in both the coil end and the spark plug end of the wire and snap them on.
The total job took me 2 hours and I was taking my time.
