AC Rapid fire # 5's work great in my 91. Also, for the P/S plugs, go ahead and pull the wheel and inner fender. SO much easier. Still need a swivel but cuts down on time.

Default Cut a small slot in the RH wheel-well

I used a dremel and made a small opening in the RH Wheel-well to allow me straight on access to the front spark-plug on the RH side of the engine. Used a long extension and I turn the wheel all the way to the right ... it saves a lot of time.

It was actually a slot on the shock tower opening.

I use NGK plugs. They were fine as I can tell. They say they have a wear coating on them that will act as anti-sieze. So they say not to use anti-seize on them even though I still do anyways.

I also use Delphi spark plugs wires. Best I have used for OEM replacements.

I don't remember the last time I changed plugs. But I always put anti-seize on them, so hopefully this winter when I change them, they won't be stuck. All these reports of stuck plugs are making me paranoid!

Kinda why I like to do it every couple of years. To make sure it doesn't stick. I know that you can get away with 3 or 4 or 5 years but one day, it will come to bite you back.

I hate being bitten in the back (unless wifey does it).
