Spark Plugs

[MrAurisT]

Quick question please. I have a 2010 1.8 Petrol Valvematic, now 57000 miles. The spark plugs were done (main dealer service history prior to my purchase 11/2021) at 30k miles, December 2016 (full 6 year service).  The car runs very sweetly, but thoughts on changing them due to the time elapsed?

Elapsed time will have no effect on them. 

I'm not sure what mileage they shoud be changed at, numerous things have an effect on that.

I would take them out and inspect them, before making a decision on how to proceed.

These should be 90919-01275  / SC16HR11 / Iridium plugs that has long life in uk 60k miles in USA 120k miles intervals. They are mileage only intervals therefore the time doesn’t make any difference.
Next change will be at 90 k miles.
