How to change spark plugs - 2003 Chevy Impala

Thanks to both hellokit and admitted amateur for theie reponses. I had gotten a quote for about $150 for this from a repair shop. Although I trust their work the price seemed a bit high. Now I understand better why they tagged on the extra bucks.

I’ll ponder this but likely end up taking it in. I’m not that experienced and could easily end up creating additional problems for myself.
