ACDelco Conventional Sparkplug is rated 4.3 out of 5 by 6.
Rated 4 out of 5 by from Great product These are great plugs, obviously since GM uses them right out of the factory. That's the main reason I like to use them as well, when I do a tune up. This time, however, one of the 6 plugs I bought was bad and I had to replace it. No big deal, I guess that happens. Can't really complain, they were a great price. Thumbs up!
