XK 2006 4.2 Spark Plugs

[Freebird Paul]

Morning All

Question on spark plugs:

I am being told by my local specialist that plugs only need to be changed every 100,000 miles! Mine have covered just 21,000 in 7 years, they were fitted by the previous owner.

I have owned the car 2 years and have been delighted with it, It starts and runs great with no issues, current mileage is 62,000 and i just wondered should i change the plugs as 100,000 will take another 10yrs!

Thanks in advance for any comment/advice.

If everything is ok then leave it alone, enjoy the car.🤙
