Hi Guys
Just a quick one. What's the life expectancy of the standard Laser platinum PZFR6F-11spark plug
Service is due and wanted to check if the plugs required changing.
I hear they have an expectancy of around 100k miles? Is this true?
Cheers All

Service Manual says 105k and 7 yrs!
I thought it was 60k and 5 yrs. I'll need to check the in car manual when I get home!

Book manual says 60k miles or 6 yrs, whatever comes first.

cheers BMCC - I thought 100k was a tad too much.

What do they look like? Any signs of erosion?

They look pretty new to be honest - slight brown ish colour - only covered 12k really so not really broken in. lol
Will just clean them up with a wire brush when I come to service next month
didn't really these plugs had such a long life. A friend told me that platinum plugs last ages hence why they cost so much so wanted to find out for sure how long they can last.
I assume if the car is driven hard it shortens its life???
