24K plugs
Decided to pull the spark plugs after haven been in for 24K. This is in a 1994 Fleetwood Southwind Storm 28ft 454 w/4L80E Surprisingly they looked very good after 24k miles.... https://www.irv2....

24K is nothing for spark plugs these days ! I'll bet the recommended interval is 100K.
Those don't look like AC Delco that came out of them.
