2006 car, 42k miles
The car started misfiring a few days ago. I was expecting to find a coil pack cracked, because heard that happens - the plastic cracks from the heat and water gets inside.
Instead I found the plastic completely gone! And the metal plates inside rusty and warped. It amazes me that they kept working as long as they did.
This is roughly what they should look like :

I had all the coil packs replaced at 39K miles. A misfire & CEL. Three came up bad, so I had all replaced. My mechanic said that they all looked pretty bad. The coil packs are known to deteriorate from road spray and on cars that are not garaged. It has been reported that, once a single unit goes down, the rest will soon follow.

Yes, Never just replace one. REPLACE ALL.
Also while you are there replace the spark plugs too.
I have a 2006 with 25k and I have replaced my sparks 2 times and the coil packs once after a missfire issue.
Also do not overtighten or you will crack the plastic and have to start all over again.

I assume some chunks of plastic are out on the road somewhere. These things are right at the bottom of the engine and totally exposed to the elements and the road. Most normal front-engine cars have these things on top of the engine, not the bottom, which protects them a bit.
