Start by removing the plastic cover over the engine (I just leave mine off). On the passenger side, remove the intake tube and the resonator. Follow the wires until you see them go underneath a cover attached to the valve cover by 4 bolts. Remove that, and there are the plugs. You will need a 10" extention to get to them, as they're deep in there. On the driver side, you'll see some electronics in your way and possibly the PCV hose. Just remove that, remove the cover again, and there are the other 4.
In addition to the above, I recommend getting one of those metal rods with the magnetic tip, so you will have an easier time extracting the plugs from the plug-wells once you unscrew them. They are available at auto parts stores for around $2.00.
I highly recommend the use of anti-seize compound for the plug threads. The threads on the Mark VIII's aluminum heads aren't difficult to strip, and a seized plug will make that more likely to happen.
Use dielectric grease on the wire-end of the spark-plug, to protect the ends of your spark-plug wires.
Finally, when it's time to install and tighten the plugs, be mindful that they don't need to be in real tight, just snug. Turn them till they seat in the head, then give them an additional 1/16 rotation. DO NOT GIVE THEM A HE-MAN TWIST or you'll be sorry. -JMiles_T

What are the best spark plugs for a 1990 Lincoln Mark VII?
I used Autolite spark plugs in my Mark VII. Autolite is the retail version of the factory Ford part. Same as ACDelco and GM. Im sure you've seen tons of different plugs out there and some of them are great I like at bosch platinum plugs but they are a waist of money unless 1) your car came with platinum plugs 2) You have or are planning ignition system upgrades. But for a stock car use factory plugs. Also make sure the plugs are gapped correctly. Even pre-gapped plugs, Ive seen pre gapped plugs almost .015 off the gap.

Why does Jeep recommend to change the spark plugs on a 2005 Jeep Liberty at only 30000 miles?
30,000 miles is recommended for spark plug replacement on all Chrysler/Jeep vehicles, not just the Jeep Liberty. Not only are plugs recommended at 30,000 miles, shock absorbers are recommended as well. As a mechanic for the Chrysler/Jeep Corp., i can say with confidence that it is not entirely necessary to change plugs and shocks at the 30k mile mark. Basically, "If it ain't broke, don't fix it!" (however, i do recommend at least checking the plugs at 30,000 miles)
