Can you confirm that the centre metal electrode is still in the plug, or not.FYI how they're made How It's Made - Spark Plugs - YouTube
As others have said The centre electrode and the insulator looks missing in that photo.Does the plug look hollow now?Can we see photos looking at the plug from both the top and the bottom please.Oh and it does look pretty old anyway

Will try to upload another photo Imgur][img]http://iI always change my plugs at about 20,000 miles (+/- 30,000 km) just to be on the safe side and get a good burn.If the plug isn't hollow then only a bit of the lower insulation has fallen off and that could have been happening gradually over a period of days or weeks.Put new plugs in and drive it like you stole it for a few miles. Oh, and check the oil. If your mechanic skimped on the plugs maybe he cut a corner there too.
The centre electrode is there but we could do with a photo looking inside the plug to see how much of the insulator is missing
I would chance my arm and fit a new plug and see what happens
looks intact, jut need to look how much of the insulator is missing, fingers crossed it's just the tip
If someone brought a car into me like that, the first thing I would do is a compression test, and if the compression psi is in line with all the other cylinders I'll fit a new plug and fire it up to see if there's any abnormal sounds. What we dont know if HY have done this already and found that the compression is down, leading to a holed piston or a bent valve and if this being so would require the head to be removed for further investigation.Or maybe they just looked at the plug and said we will require the head to be removed, easy money for them as they already stated voided warranty

Is that the original factory plug and if so, what is the code number on it. I see a stamped five in the first photo. If that is the last number of the model type that is a 1.3mm gap where the Hyundai i30 plug should end in a four, denoting a 1mm gap (according to champion website)
