Looks normal to me other than the residue on the plug, have they been in long? Just looks like they have a lot of miles on them. Mine are probably worse, they are still factory with 114k

is it an iridium plug? Iridium plugs are shaped different. Did I spell that right?? What do you see that doesn't look right to you?

Looks like a clean burn.

I used the tr5ix's and it was a noticeable difference. Took me about 3 hours (mostly the rears) to do. Defiantly worth the money. My car has 92k on it and when I pulled them they sorta looked like that (not nearly as bad).

get the iridiums... TR5IX for stock heat range... or if you're gonna get a tune at all, go with the TR6IX ones.. they're one heat range cooler...

Iridiums last from 75K - 100K miles, that's why they are so expensive. Copper plugs last about 15-25K (some more some much less) which is why they are dirt cheap.

Why LMAO? Those back plugs were a bitch to change. Little room and you have to have the right socket wrench and extension (which I did not have) to get back there. I scraped my knuckles pretty bad on the back exhaust manifold.
