You got the cheap bastard part right.It was a good lead-on hips. You win. There are reasons to change a single plug - you are working on something, wrench slips and wacks a plug. "hmm, should I trust it or replace it?" Or the one bad cylinder that keeps fouling a plug . . .
You're still a cheap bastard

Should really get the fittings and things to do a proper leakdown test but now I don't have to so hey that's less shit to buy.
Thing has been a good truck but it's gotta have 350k or better on it now (it stopped counting years ago).
Time for a mid-life makeover. Little nip-n-tuck. And a daddy stitch or two.
