Old plugs out new in
More of a success post! 2019 with 55k. Changed out the old plugs and went much better than I expected. New plugs came in at 0.026 even though Rock Auto and GM lists them at 0.03.... which was just perfect. The old plugs were a tiny bit ashy with not bad carbon buildup. Running good with the new ones! If you haven't changed em go for it!
