Hard to say, really. Could do with seeing the porcelain and how shiny the plating is on the metal parts (that aren't inside the cylinder). The electrodes don't look too bad really - maybe a slightly large gap. Worth checking it with feeler gauges. Hopefully, someone will be along to quote the correct gap soon.

If they weren't changed 2000 miles ago, how old would they be, roughly?

I've just removed some from the Panda after a year but only about 5000 miles and they look so much better than yours.
Your centre electrodes are rounded and the gaps are enormous. If this is 2000 miles they'd be seriously defective. However, their general condition and colour look fine, so not showing any engine issues. Hopefully you've changed all four, not just the three pictured.

You will get no joy with the garage after this time. Whilst those plugs don't look new enough, the car has been out of their control for 2 months and 2000 miles, during which time anything could have happened. They'll claim those are not the plugs they fitted, you can't prove they are. Not worth the bother. For the price of new ones, just wear it and enjoy the car.

Can't see what plug number they are, gaps differ. The later plugs for the Panda are pre-gapped at 1.0mm. I think the earlier ones are 0.8mm. No point regapping these, just replace them.

I cant get any better pictures that those but one one of them the insulation around the electrode was absolulty shot. That one looked really old and the other 3 looked bad but not as bad. The thing im more conecered about is that when i got it serviced i paid for a timing belt change cause the belt has about 74k miles on it and if they never did the plugs im all but certain they wont have done the belt as well. ****s!

I did i just replaced all 4 of them, people kept on saying to me that it might be the spark plugs but thinking they had just been replaced i dismissed it. I bought some just in case and luckily they came in handy. The part number was ZKR7A10 if u were interested.

If the belt is that new it will still look new. If it is the original, that will be obvious to a good mechanic. Ask another garage to just look at and confirm whether they think it is a new belt. This can be done in minutes, as the belt is visible enough from underneath without removing anything. They may wish to remove the top cover for a better view, should not cost much.

Meanwhile, keep the removed plugs. If the belt is old, challenge the garage, for either your money back, or the job done properly. (I'd prefer money back, as why would they do a good job second time.) If they won't refund, pop into Trading Standards for a chat about it.



NKG list this as ZKR7A-10. The 10 at the end relates to 1.0mm gap.
