The plugs are under the 8 individual coil packs on top of the engine.
If you have C.O.P ( coil on plug ) then the plugs are under there. Just remove the coil, pull the plug cap off and there you go.

To change the spark plugs on a 1999 Crown Victoria, first ensure the engine is cool and then disconnect the negative battery terminal. Remove the ignition coil packs by unscrewing the bolts and carefully lifting them off the spark plugs. Use a spark plug socket and ratchet to remove the old plugs, then install the new plugs by hand to avoid cross-threading, tightening them with a torque wrench to the manufacturer's specifications. Finally, reattach the ignition coils and reconnect the battery terminal.
