spark plug replacement

Hi hoss4sum and welcome to the Lincoln Forums. What about spark plug replacement? When should they be replaced?
If yes...the answer is at 100,000 miles, according to the Lincoln Maintenance Schedule. However, replacing them sooner certainly can not hurt.
If you do not have the Maintenance Schedule for your 2006 Zephyr, you can download it here: https://www.fordpro.com/en-us/fleet-vehicles/manuals-and-guides/

If you are looking for some other type spark plug information, please be more specific.

Good luck.
