Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace an ignition coil on this 2004 Ford Crown Victoria with the 4.6 Liter V8 engine. The items that you're going to need for this include a new ignition coil from 1AAuto.com, a 7mm socket and ratchet, and if you're working on the driver's side ignition coils, you're going to need a flat blade screwdriver.
Now, on the driver's side, your ignition coils are covered up by this intake hose. You just have to loosen up those two hose clamps with a flat blade screwdriver and pull it free. Then you can access all four of those ignition coils.
On the other side the ignition coils you can access right now we're going to show you on the easiest one to see so we can show you the process. Just push the tab on this harness and pull it free. Then you want to remove the 7mm bolt. Once the bolt is removed, you just pull it forward, up, and out.
On the left is the old ignition coil; on the right is the new one from 1A Auto. You can see they're identical, and they'll mount exactly the same. Push your new ignition coil down into place, and back. Then replace that 7mm bolt. Once you've tightened it up, reconnect your harness, and you're all set.
We hope this video helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.

Brought to you by 1AAuto.com your source for quality replacement parts and the best service on the Internet. In this video we're going to show you how to remove and install a new coil in this 2011 Lincoln Town Car. This has a 4.6L, the same as many of these vehicles. The tool you'll need is a 7 mm socket with a ratchet and extension.
With your 8 mm wrench disconnect your negative battery cable.
Okay, replacing your coil and spark plugs is 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 a couple of hose connections on the back and you remove that whole intake hose and get to your coils pretty easy. Okay, so the coils are held in place by a 7 mm bolt. Get the socket ratchet down on there. It can be a little tough to break loose. I'm just going to get my socket off of here before I get too far. Okay, 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. This happens to me a lot. I've removed a bolt but it twisted in the socket so it's now stuck. 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.
Okay original coil. New coil from 1A Auto. You can see pretty much all the same. It has the same connector and everything. Put it right down in. Press it in. Okay your 7 mm bolt. Reconnect your lead, you're all set. Just repeat that for the other seven cylinders. Then reconnect your battery and your engine should be purring like a kitten.

They look great being red, don't think it'll make it run any better, but it looks great ! Easy to install except for the rear plugs, but they're hard to get to on most vehicles.
Perfect fit. Finally had the valve cover gaskets replaced on my 2008 f150 5.4 with over 306,000 miles and had mechanic go ahead and replace the could while he was in there.
Great quality no issues whatsoever
Work out for me and I can't even say anything bad about the way they were making everything right for the customer support is great
