Is it not listed in the O & M Manual...? Then just do a google search for that listed. You can answer your own question.

The iridium spark plugs are supposed to be good for 60k miles. I changed them on my Saturn Ecotec engine at 50k miles and they still looked just as good as the new ones.

Manufacturers say the original plugs will last 100K miles.

I have taken out plugs that had 100K on them, yes they still look good,

I changed the plugs on my neighbors Buick, the owners said the car felt like it had more power, with a fresh set of standard plugs.

Plugs take an awful beating, for 8 to 12 bucks, I think changing them every few years wouldn't be a bad idea.
