Depends on the type of spark plugs. Factory plugs around 70 - 100k depending on the condition of the plugs. I would replace the spark plugs out with some AC Delco iridium plugs they will last you 100k+.
Standard spark plugs, 50000 miles. Platinum tip spark plugs, 100000 miles.
If you have platinum spark plugs, 100K. If you have standard plugs, 50K.
when do you change spark plugs
You should replace your spark plugs at about 60,000 miles if you drive your car rough or as they call it "lead foot". If not you should be able to get about 90,000 out of them. Just remember that the sooner you change them the sooner you can get power and fuel economy back.
Generally I change platinum plugs at 100K and regular plugs at 50K.
