exactly what I was going to say.... after owning a Chevy truck with large headers on a 350... I must say, this 4.6 has got to be the easiest engine to change plugs on.. Do be careful though, not to drop anything down the plug runner, or you'll be wishin you hadn't... Now for the one on the pass side under the fuel rail, what you can do is assemble the socket inside the rail... Take your socket and drop down in to the hole with the plug.. then use a slender extension to slide in from an angle and then link up to the socket, use a U-Joint piece to make the bend, and this will all you to remove it... Then use a small section of rubber hose to remove the old plug and install the new one... Works for me, I have the whole engine done in about 15 minutes..... But I don't have to gap my plugs, I use the Bosch +4 ( what used to be called Q4). Just make sure you are careful not to let junk/build up and other tools to fall into the plug opening.....
