That's a very pretty ST.

Ford bestowed these motors with long life plugs.  Yours may be on its second set by virtue of mileage.  If its driving fine there's little point replacing them, but when it's time for a service then you could slip some in.

Again, if it's driving fine I'd be inclined to leave the leads alone.

Thank you I love it 👌Yeah car drives normally, so on next service I should change spark plugs? Original ford or these from euro NGk?

Original Ford can be had very cheaply if you ferret around on the internet.  Not everyone in the spanner trade likes NGKs, but I'm fine with them.  Denso are also good.  Buy whichever of the three is cheapest.

 

If that car is looked after as good as it looks you'll have little problem.

Beru have always been my choice.
