Works as advertised.
Installed in a 2014 GMC Terrain: is same as OEM spark plugs. Lubricated threads installed and so far, no issues. Installed 3 days ago, drove around some so the system can acclimate. Now, everything is working better than before install.

All five perfectly gapped.
If this is the OEM plug for your car I can tell you that after 68,000 miles of service on a stock engine the gap between the center electrode and the grounding electrode grew about .0015" for this plug. The outgoing plugs had a gap that I would call a sloppy .034" since a .035 feeler gauge would not pass with out undue force. The new plugs received fro Amazon were all gaped at a perfect to my hand and feeler gauge .033". The factory install plugs were not coated in anti-seize and uninstalled nice and easy, all requiring the same 550 in-lbs to break and were smooth to spin out by hand via extension shaft and plug socket after being broken of seat. Excellent plugs and really the only thing you should be running in your LNF. I am pretty confident these plugs are a true blue 100K+ mile life cycle item. I bought one extra because I knew the shipping department was going to haphazardly into the box with the new spark plug socket set I ordered at the same time and didn't want to delay my plug change because of the predictable, they have done similar things to me before. Fortunately, although one plug came out of its box and had a socket sitting on it, ACDelco included a plastic tube sleeve to protect the threads, electrodes, and ceramic and their .5¢ protector in the packaging saved me and Amazon from having to process a return despite Amazon's continued consistency in variable packing quality, consideration.
