I'm going to use my 20+ years' experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly, that's going to save you time and money. Thank you and enjoy the video.
In this video we're going to show you how to remove and replace spark plugs on this 2000 Lincoln Town Car with a 4.6 liter. Tools you'll need are a 7mm socket with a ratchet and extension, a 5/8 sparkplug wrench or socket with a ratchet and extension as well, and you will also need a spark plug gapping tool.
Take an 8mm wrench and disconnect your negative battery cable. Replacing your coil and spark plugs- pretty easy. I'm going to show you on this side because it's easier to film and get to. The other side is just as easy. You do just need to remove your intake hose which is three clamps and another couple of hose connections on the back. Then you can remove that whole intake hose and get to your coils pretty easy.
The coils are held in place by a 7mm bolt. Get the socket ratchet down on there. It can be a little tough to break loose. I just want to get my socket off of here before I get too far. This connection, you just reach underneath and there's a little tab right here. Squeeze that tab and the harness pulls loose. You can just kind of pull your coil up and out like that. To get your spark plug out I've got a spark plug socket. It's a 5/8 spark plug socket. It's designed to grip onto the plug although I know mine is pretty worn out so I'm just going to put a little piece of paper towel in there and then you can put your wrench right down in. There's usually a little bit of angle. Break the spark plug loose.
Just fast forward through loosening that and then what happens is I actually get another piece of paper towel just to stuff in there to grab onto the spark plug. There's my plug. You can see these plugs are in pretty rough shape. Here's the spark plug we took out, and then here's the new platinum tip. You can see that there is quite a bit more to the new plug than the old one. This one is pretty worn out. On this Lincoln Town Car with 4.6 liter, you want to make sure that the gap between the tip of the plug and the diode is at .054. My gauge only goes to .050. So we're just going to have to just say the .004 is going to be okay which I'm sure it will be. I don't think the engine is going to mind a .004 difference in gap. What we can do is, let's see here, so we use this part of the tool to kind of bend that diode, and then we run the gauge through, and we want the gauge to basically go through and have a little bit of drag. Then that will be fine. That's .050 which is only .004 off which is perfectly acceptable. Again, I have a spark plug wrench. My wrench is a little worn out so what I'm going to do is wrap paper towel around it, stuff it into the wrench, make sure none of that paper towel was down near the threads or anything so that it sticks in there.
Now I'm going to put it down in and I'm just going to kind of lightly turn it and it goes in. When you're turning this in, it should offer some resistance, but it shouldn't be hard. If it's hard to turn you may be cross threading although it's a little hard to cross thread these plugs. Then these should be tightened to about 18 to 20 foot pounds, which is just kind of tight with the wrench like that. This happens to me a lot. I've removed a bolt, but it twisted in the socket so it's now stuck. So what I do, I take a screwdriver or something that fits right up in there, let's see here, and then I just drop it and basically that usually almost always gets the bolt from the socket. Just make sure you watch where it goes. Put is right down in. Press it in. Your 7 mm bolt. Reconnect your lead and you're all set. Just repeat that for the other seven cylinders. Then reconnect your battery and you're engine should be purring like a kitten.

The OEM spark plugs will be iridium but can be replaced with a different aftermarket design as long as they are correctly listed for your vehicle.
