My 00 vert hasnt had the plugs changed in its life yet, Im changing them here soon. Are these Iridium plugs the way to go? Car has 63k on her.

I've been running NGK TR-55s gapped at .055 since my first plug swap at around 30,000 miles. I have 80k now swapping them 15-20k. Zero issues lots and lots of hard use (HPDE use).

I have only 13,500 mi on my 02 coupe. I know they are the original plugs and wires and have lots of miles left on them. My concern is they have been in there for 7 years. Should I change them?

Going by the service manual, plugs are changed at 100K miles, and wires inspected. At the very least, I would pull the plugs and inspect the condition. Also check the wires for the same. If you do decide to change them out, and stay stock, you are looking at ~$100 for plug/wires....not really a big deal if they last you another 7 years...

I purchased a set yesterday for my '01, and they gave me 41-110. A search on the AC Delco website, shows that this is the correct plug. A search for 41-985 turns up nothing???
