OEM spark plugs life?
When should I change the OEM spark plugs? I was planning to do a compression test for the car, and think it might be a good time to change the plugs as well. Sorry for asking this, but I have a JDM-spec car and it didn't come with a maintenance guide.
BTW, the car has about 7K miles.
