03 Mach 1 - second owner
Cold air intake, off road x pipe and catback
Per the original owner, the car has the factory tune.
At 16,000 miles, we changed the original plugs.
8 of the spark plugs, the ground electrodes are charcoal to gray in color.
5 of the spark plugs, the white porcelain around the center electrodes are red or pink
2 of the spark plugs, the threads have a little oil.
What are your thoughts based on the condition of the spark plugs?
Note: Graphic of a spark plug that labels the electrodes.
