I know the interval for factory spark plugs being changed is 18k Miles, but I’m sure there not worn out at that ?
Has anyone ran them longer than 18k and if so what condition was they in?
What is the most mileage I can get out of them ?
can you run them till 30k or has anyone ran them that far ?
Thanks in advance, Im trying to extend replacing them till after my upcoming trip!
