Tune up

I want to do a tune up...plugs, cap, rotor, wires. Anyone got some plug recommendations..Brand, type of plug? There are so many types these days...copper, platinum, iridium etc

I run NGK TR55's with good results

I think Delco plugs are made by NGK. I just did a tune up and used Delco Iridium plugs and she loves it

ACDelco 41-993 should do nicely.

I just did plugs and wires on my 00 and my advice would just be to stay away from parts store brand parts. stick with reputable companies, buy acdelco if its in your budget those parts were made for your motor. Another word of advice is to stay away from crazy plugs like e3's or multiple electrode plugs. In my experience they are nice right out of the box but they dont last neer as long as stock replacements. Plus they are nowhere neer cheap!

as far as cap/rotor get 'em w/ brass/copper contacts if possible - they seem to last longer than ones w/ aluminum contacts.
for spark plugs, nothing wrong with the copper-based ngks (TR55) or acdelcos (R44LTS6).
