Factory plugs are platinum tipped. That's what gets you the 100,000 mile change interval. Non-platinum will work, but won't last as long.

No clue on price of a tune-up. Never paid for one. :noidea:

well if there are plats then the plugs should be good . the car has 42,000 . the cap & rotor had corrosion so glad to replace those as they were alum and not brass .got a lifetime one from az .. do you think the plug wires are still good ?? they were flexable at cap . would age hurt them??? car feels like its at a lower rpm now at idle

The later years anyway if not all were platinum.
It shouldn't too much, maybe an hour labour or so if they are doing all of them so should be a bit less for just the rears. They can be hard to get to.

Hard to say about the wires. They are affected by age, but if it is not misfiring, they're good. If it ain't broke, don't fix it.
