Do you replace the coil pack when you change the plugs..
Not unless there is a problem with the coil pack does it need replaced. Some vehicles coils will last about as long as the spark plugs and may be recommended to be replaced at the same time. Most vehicles spark plugs are changed between 90,000 and 120,000 miles. Some vehicles require a lot of labor to get to the plugs and that would be a good time to change the plugs and coils at the same time.
