How to Change Spark Plugs in a 2004 Ford F150?

There are several steps to changing spark plugs in a 2004 Ford F150. Firstly, you need to open up the hood. Place a vacuum hose inside. Then, apply anti-seize to the threads of the spark plug.

If the spark plugs stay in the vehicle, you can re-tighten them a fraction of a turn or use more penetrating oil. Afterward, remove them from the vehicle.

Remove the spark plug shell. Turn the fuel injectors to one side to provide more space. Remove the COP connector. Some spark plugs are incredibly tight, so you may feel like you can’t remove them. Use a 7mm wrench and a 9/32″ socket to remove the COPs. You should be able to easily remove the spark plug shell, but some COPs are so tight that you can’t pull them out. To make sure you don’t damage the spark plug, you should use a special tool to remove the COPs.
