You have to take into account that the body on an E-series completely surrounds an engine. Unlike a truck or a car, where you raise the hood and expose most of the engine, a full size van body covers most of the engine. Even with the "dog house" cover removed from the inside, and the hood open, only a small amount of engine is exposed. The top of the engine, where the spark plugs are accessed, is still completely covered by the body of the van. Add to that, the fact that each spark plug is covered individually by a coil that is held down with a very tiny screw that is very difficult to access due to the fuel rails, wiring harnesses, and hoses, and you have a very time consuming, tedious, and difficult adventure ahead of you. Even with the coils out, the spark plugs are located about 4 inches down inside of a spark plug well, that requires a special socket to access, with barely enough room above the engine to fish the socket down into the hole, and back out. Of the available engines for that vehicle, only the V-6, 4.2 liter engine is easier to replace the plugs on, but it still has an increased level of difficulty over a truck as well.
Today's diesel engines do not use spark plugs.Today's diesel engines do not use spark plugs.
Yes, all gasoline engines must have spark plugs. Only diesel engines do not require spark plugs.
the plugs on the back are very difficult. How is this done.
when do you change spark plugs
No. There are not "spark plugs" on turbofan engines. There are ignitors, which help to ignite the fuel during start, but unlike spark plugs, ignitors do not run constantly.

ALL gasoline engines have spark plugs. Only diesels don't have spark plugs.
I don't know why you couldn't change them, no matter where you are.
Both V6 engines have 6 spark plugs
It can be complicacated since on some models the spark plugs are difficult to get to but I would recommend to find the spark plugs first and then double check to make sure you know where they are.
