131k miles on original plugs
My brother in law was visiting, and he also has a 4runner (his is a 99). He told me that his 4runner wasn't running so well, so I suggested that we change the plugs and clean the throttle body. While changing the plugs, I noticed that there was a lot of resistance unscrewing them. Once the job was finished, I then noticed that 3 plugs were NGK and 3 were Denso; just the way the 4runner came from the factory. No wonder his 4runner was running rough. It went 131,000 miles on the original plugs! The old plugs looked really worn too. It's not all my brother in laws fault, though. He bought the truck used with 100,000 miles on it.

He recently had the oil and air filter changed. His brakes need changing, though. I'm going to help him do that in 2 weeks. I'm sure his timing belt is the original. I did tell him to have that changed real soon; It's more work than I care to do. I hope it doesn't snap on him soon.

i just changed mine, i dont think they have been changed for a while. The wires came out in a few pieces each.
I had noticed recently that my car ideas a tad rough, so i decided to change plugs and wires.
This is what my old ones looked like, and i think the worst part about it was pulling them out and reading champion on the side of the plug
They were gapped at .055 a little off from the .032 on the 2.7

Had my factory plugs on my Celica (2000 GT) about a year ago, 137,540 on the factory OEM plugs. My milage had slipped some down to 33mpg around town. After, it went back up to 35 and I get around 38 on the highway ... now if I could only get my truck to get that kind of milage!
