What (if anything) do these spark plugs tell me, about the condition of my engine?
Hi all,
Just serviced my beloved 2013 R56 JCW.
These Champion 12ZR-6SPP2-1 spark plugs were main dealer fitted, in Sept 2017 at 19,602 miles.
My car now has 40,446 miles on it, I replaced the Champion with Bosch Iridium ZR5S1332.
I change my oil every 12 months/5000 miles.
Any helpful comments would be greatly appreciated!
