The spark plugs themselves seem solid, and they fit my LS1 perfectly. My only issue was that the shipping took longer than expected. I was ready to install them right away, but had to wait an extra week. Otherwise, they perform well!

Great Upgrade for My LS3
I swapped out my old spark plugs for this AC Delco set on my LS3, and wow, what a difference! The engine runs smoother, and I can feel the power increase. Installation was straightforward too, which is a plus for someone like me who isn't a pro mechanic.

One plug failed after short use
I was excited to install this AC Delco set in my LS6, but one of the plugs stopped working just a month in. It's frustrating because I expected better quality. I might try a different brand next time, as I can't afford another failure like this.
