Fixed Acadia misfire
Cured the occasional stumble/misfire I was experiencing on my 150k-mile 2014 Acadia. No fitment problems as a replacement for the stock ACDelco plugs.

Perfect fit
These spark plugs installed without issues on my 5th gen Camaro. They fit perfectly and they function without issue. I haven't put many miles on them, but they keep my engine idling a lot better than the replaced spark plugs. I can't comment on performance just yet, but I expect that they will meet the performance of the original spark plugs.
