My 4Runner came with over 14 years of service records and none suggest the spark plugs were ever changed :noidea:
Just bought some OEM plugs and NGK wires and went to town. The driver side rear plug did not require any removal of brackets or tubing and I was able to get an extension in there and into the plug without issues.

Okay, so these are not OEM so it has been changed but never documented. They're NGK's and look like they've been in there for a while:

The intake tubing had to be removed for the passenger side but this was such an easy install compared to my 2nd gen that was covered with vacuum tubes on the passenger side:

I hear that these engines eat plugs up pretty fast if it's a single gap. I'm happy to be replacing the NGK's with OEM dual gaps:

And in less than 30 minutes, we're back in action:

*Just took it for a spin and it already feels better. *While I was in there, I noticed that the PVC grommet/valve looked old and that's going to be on my list for when I also look into the timing belt and water pump.imp:
