ACDelco Gold CR43TS (19302741) Conventional Spark Plug (Pack of 1)

Very good quality. Worked perfectly.

Works good

These spark plugs probably work fine. Sold the truck before I installed them, and now they just stare at me all crestfallen from my work bench.

Good plug good for the money

Used these for 10 years took them out to replace and compared to the new ones.. Well the platinum centers are still square after all those years they look new. i think i coulda got another 10 years out of these for how little i drive the truck maybe 50K miles on those plugs could have easily done 100K milescompare that to some iridium plugs that were 10 years old in a mazda that the center post was completely eaten away.Sometimes the old stuff was just made better , higher quality metals and a performance history to back it up. I always try to get OEM and Ac delco is almost always the OEM part for my 1990 GMC ,

Everything great !!!

They worked exactly as described

OEM plugs fit and function fantastic. I put them in a 1992 K2500. Remember to gap your plugs according to your application. Mine was .035, they are not pre gapped out of the box.
