Believe it or not, the easiest way is: 1. Remove the plug wire by pulling it off carefully, grasp it close to the end. You can also buy a plug wire remover which is available at any parts store. 2. Using a SPARK PLUG wrench (available at any parts store) - remove the old plug. 3. Insert the new plug. 4. Tighten, but not TOO tight. 5. Push the plug wire back on. 6. Repeat 1-5 for the other 7 plugs. You might find it easier to access some of the plugs via the holes above the tire wells. From the side of the vehicle, you'll see a hole near the top of the tire well. If you change the plugs, it's best to replace the wires also. NOTE: The wires and plugs on Grand Marquis are rated for 100,000 miles or more with proper maintenance. NOTE 2: Unless you area good mechanic, changing the plugs can cause you more heartache than the price of having a professional do it for you. With all the Computerized stuff on 2000 model year and later automobiles, it's best to pay a price for a complete tune-up. Good Luck -tj-
