spark plugs?
I have 8000 on the plugs and my car just developed a little hesitation and a slight backfire.
I pulled out a couple plugs and they look good but should I replace them every 5000 or 10,000 miles.
Thanks for your help.
what plugs are you running?
standard spark plugs last ~25k or more
the platinum plugs last 50k or more
and the iridium last 100k
I hope you are running a one step colder plug with that forced induction. Such as a NGK TR6
