Some background info:
04 4Runner V8, 255,000KM
Reason I'm asking is because the original plugs from factory are Denso Iridium which are good for approx 200,000KM (as per online, 120k miles).
These ones I pulled are NGK Iridium, so assuming they were changed somewhere near where the recommended interval is, they should still be fine.
Previous owner was pretty good with maintenance and kept most of the records, but I can't find any record of when the spark plugs were actually done.
