Default spark plugs?

How often should I change my plugs with a D1SC?
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.

uumm unless you are fouling them out or they look bad I wouldn't change them.

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
