I have 17K miles and two years on my current set of NGK plugs. Is that considered accenpatble?
How often to change plaugs?

For a stock engine, every 30k is probably often enough.
Let me ask one follow up question, please.
Is it worth the time and effort taking the NGK plugs out and cleaning them and/or regapping them?
Thanks,
Pat
If the car is running fine, no. IMHO. If it ain't broke...
