2014 scheduled maintenance

Chevrolet recommended replacing the spark plugs at 98,250 miles. I debated replacing the plugs for a few weeks. I could see no mileage, performance or drive-ability issues.

I had the plugs and wires replaced (by the dealer) at 99,550. I'm not that much mechanically inclined but I now believe replacement was needed. See picture.

The plug actually (IMO) looks pretty good for nearly 100k- no real build up. Did you see the gap on the new plugs vs these? At any rate, it is great that you enjoy and use your C7. Cheers!

No, I did not think to view or photo the replacement (new) plugs and cannot comment on the gap distance.

And a big YES, the car continues to thrill me daily.

I think replacing was a good idea, not just because of the scheduled maintenance but my concern would be gaulding or seizing in the aluminum cylinder heads if left too long. Thanks for sharing.
