GM recommends 100k on the spark plugs. If it were running bad, missing or getting poor fuel mileage, I'd be inclined to change them. As it stands, it's doing just fine.

No need to be irate. Just questioning changing plugs in a modern car with such little mileage. Changing them in a P5 would certainly be easy. Getting to the rear bank on my Regal is not. I'm not going to do it any sooner than necessary.

my g/f's old (01) sentra gxe said to let the plugs go way over 30K. i believe it was like 60 or 75K. it is such an easy change and costs almost nothing i did them at 30K like when i do mine. can't hurt.......
GM does recommend their plugs for 100K. I had a 2000 Sonoma. The plugs were the only things that did not fall apart break, or otherwise end up at the dealer for a problem with. So 100K is great, if the whole car makes it up to that mileage. At 50K, it became 2 Mazdas, and someone elses financial burden.
I swapped outthe factory plugs at 15K for Bosche triple platinum plugs. Afterwards,a nd months later, I read how bad these plugs are, but I did not have any problems. I installed an AWR mount Saturday night (thanks MelbourneP5!) and on Sunday, I noticed the whole friggin car shook like it was an 82 Honda with 400K miles. Even the windshield wipers shook violently. I understand the SWR mounts make you feel some vibration, but this was absurd! I went and got good ol NGK's, and popped them in. It purrs like a kitten now. a slight vibration, but nothing to complain about.
Oh, the Bosche plugs were ******* wasted. Total garbage. I will only put them in an old VW, that is all they are good for.
So put air in your tires, go get them fixed or upgraded, and get some new plugs. Took 5 minutes, and is the easiest form of maintenance.

Just for you guys, I'm going to take a look at the plugs on my P5 as well as my Regal this weekend.
I'll get back to you with the results, but here's my prediction:
Some of the Regal's plugs may be missing the platium puck on the electrode. I've seen that before on my Z28. It really enlarges the gap, but the coils are powerful enough to make the spark jump it. I'll go ahead and replace them since it's got 90k. The P5's plugs will look like new, and I'll put them right back in.

yea seriously guys why would there be any wear or deposits on the plugs after ONLY 30k miles in a combustion chamber at 1600+ degrees C and 2000 or so psi
so you'll spend the time to actually take the coils off and the plugs out to look at them, new plugs cost just about nothing, but yet you don't deem it appropriate to just throw in new plugs
looks to me like you're already making the effort anyway, spend the $4, really

$4 for plugs>?!? no way. These things cost a fortune! $6.79 at Auto Zone for the NGK's. That is a LOT more than the $4 you quote....(burnout)
J/K. Plugs are cheap. Swap em if you make the effort to look at them. Oh, and for the ******* LOVE of God, do not use Bosch Triple Platinums, they are garbage.
