Search for the term "spark plugs". It yields quite a few threads with a bunch of opinions. I am currently using Denso Iridiums. I am happy with them so far. They seemed to smooth out my idle. As for the "best", your going to get different answers.

A good cheaper plug will be the NGK 6097's. I ran it without one issue for a long time. Now I have the NGK Irridiums, but they are about $45.00 instead of $10.00 for the 6097's. They definately make my car idle better, but I haven't had them on the dyno to see how they perform in the higher rpm's.

Autolite 3923s. They're like $1.32 a piece and work great. MDC recommends them, too.

Don't try to gap them, but if you do be very very careful.

Some people with experience a little misfire with these as they are about 1/8th" shorter than OEM plugs. I had this issue, switched out to NGK's without changing anything else... No misfire.

^ And - Only $1.50 at O'Reilly for NGK Traditional spark plug 2330 BCPR6ES .032
Which is the correct height = JIS

Check out JIS (2.086") vs. ISO (1.98") height here http://www.sparkplugs.com/glossary.asp?kw=JIS&manID=0&pt=1
