Does this spark plug look newer?

So ever since I've had my car I wanted to make sure it had Iridiums in it since the guy who had it before me took it somewhere to get it tuned up. He had documentation of a tuneup that does indeed say Plugs + Wires, "oiled TB" and replaced oil pressure sending unit, all for $300. This was done at 104,800 on 8/12/2011. Today at 109,500* miles and on 3/31/2013 I pulled the front middle plug and took a look at it. Does this plug look like it has 4,700 miles or 109,500 miles? And yeah the plug wire clip ripped off, it's on there good. I did indeed pull from the boot only, and that still happened.

It doesn't look like it has 4000 miles in it. I'd say a lot more.

4,000 miles or not, they look to burning ok.

when ever i buy a used car, first thing i do is a tune up. so i start my own records.

That plug definitely has much more mileage on it. I've never heard of oiling a throttle body either. If he paid to get it done, he got ripped off.

Hmm, well I was thinking they looked more-so stock too. Yeah, Oiling the throttle body was something I didn't understand either. I did take it off to clean it a few days ago and it had a nice layer of carbon, not nearly as bad as a 3.4L I did with 115,000 miles. I guess I'll pull a few more plugs and make sure they're doing okay since I bet they're stock. What do you guys think of the sand blaster spark plug cleaners? I used it on that one spark plug I pulled and it cleaned it up pretty well. Not sure it really made a difference since the tip of the electrode was already carbon free.

Just replace them.
