340,000+ Mile Spark Plugs can be a PAIN

2006 Chevy Suburban Z71 with 341k miles.
The maintenance records show the spark plugs were done at 102k.
However, they were either new old stock or only one was done.
This was hilariously difficult for an easy job. But come enjoy my frustration with me.
I hope you enjoy it.
