But its actually not.Replacing spark plugs is not hard and can be easily done.
You do not need to remove the valve cover, only the intake manifold has to be removed. The plug wires can feel stuck, but a good tug will pop them out if the spark plugs.The amanti should use 3 coils for the spark. 3 are on top of the spark plugs and the spark plug wires run off of those ignition coils to the other 3 plugs. 1 ignition coil on the motor gives spark to 2 plugs in the motor. And they are under the rubber wire.
Sometimes a pair of pliars are needed to remove the plug wires. They just get stuck on due to all the heat cycles from the engine running and shutting off.
