    I have 20,000 miles on my Denso standard copper plugs. Mileage is around 23mpg, starts and runs good. How many more miles can I get out of the plugs before I change them?

    I've heard one person puts 60,000 miles on a set of copper plugs, others say they are usually only good for 25,000.

    You could probably get another 200,000 miles honestly. When does the performance actually decrease? Idk. I’d just go with the factory specifications. Personally I’m changing mine every 25,000 miles.
