Default Spark Plug Analysis

Hey guys! Any chance I can grab a quick second opinion on my plugs? I just changed them after getting the car in April so I dont know how long these have been in there -- but the car is currently at 54,711 so I wouldn't be surprised if they were still the factory plugs.

Thoughts?

2 looks like it wasn't tightened all the way. Other than that they look pretty good to me.

they look like they everything is operating normal in the combustion chamber. Like Slowcrash mentioned, it is a good thing you got #2 plug out of there, I think it was close to burning up the coil and backing all the way out, probably loosening up ?

I wonder if that is what was causing it to drop RPM to about 400 if I tapped the throttle at idle? It no longer does it after this. No clue if that would have fixed it, but it appears to have! Now I just have to figure out my last issue. Can't believe how pristine this car was...

Thanks everyone for the input!
