Found out today that last year when I changed my spark plugs I used the wrong ones.

I changed them with NGK coppers. Guy at Autozone informed me that they're supposed to be iridium. Got them changed out today but haven't fired or up yet.

Finally off to my question.
Could using the copper plugs have damaged anything?

the copper plugs are good for around 30,000 miles

Iridium is suppose to be good for 100,000 miles
Most times the Coil used for these is hotter than the ones used for copper

You did not damage anything
unless they were cross threaded while being installed

I think that the 13's and older use the cooper plugs and the newer trucks use the Iridium. I think they changed in the middle of the 13 model year.
