Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks!
In this video, we're going to show you how to replace the ignition coils on this 2006 Ford Explorer. It has the 4.6 liter V8, and the only tool you'll need is an 8 millimeter socket with a ratchet and extension.
Open up the hood, and in the engine, there are four coils on each side: one, two, three, and four here on the driver side. You'll need to unplug the harness. There's just a little tab that you can press with your thumb and then pull. Pull and wiggle it a little bit to get it off. Then either a 7mm or 8mm bolt that holds the coil down. You see the ones on the driver side. Passenger side is obviously located somewhat in the same position on the other side.
I'm going to remove the second one back. It's just the easiest one to video. Again, push the tab with your thumb. Pull off the connector. 8mm socket with a ratchet and extension, remove that bolt. Then once the bolt is off, make sure you retrieve it. Then the coil will pull out with just a little bit of a half turn, as well as just moving it back and forth and it pulls up and out.
The new coil from 1A Auto is going to go right down in just like the original one. You want to push it down in and give it a good firm push. Make sure that the hole lines up with where the bolt goes into the intake manifold or head. Start that bolt on and tighten it up. Obviously you'll repeat this procedure for all eight, or however many you want to replace. Make sure you reconnect all of your coils, and you're all set.
Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit 1AAuto.com. Also check out our other helpful how-to and diagnosis videos.

Quality control failure
One of the coil wires was not attached. I had to remove the rubber boot, and attach the wire. It was causing a misfire, and I was already trying to fix a misfire.

These coils seem to be working well. I was skeptical of non-OEM coils after some past bad experiences, but this set looks to work well.
