My girlfriend has a 2007 Nissan Sentra with 160000 miles on it. She does not think the spark plugs have ever been replaced which leads me to believe that the ignition coils have also never been replaced. She does not have any check engine light codes for any misfires or any other problems.
I am planning on changing her spark plugs next week and I'm wondering is it worth the cost to preemptively replace the ignition coils as well? Or since I do not have any check engine light codes should I just leave the ignition coils alone?
