I just got 4 04 coilpacks for a buddy for ~230 brand new from honda, f paying autozone 100 for 1
I'm curious as to why Honda sells the '01 coils for $89 a peice, and the '04 for $45? I'd really like to know what change they made internally. If you go by '01 coil prices, the autozone coil is a good deal being it's available the next day. They do sell a +04 equivilant for 90ish which is a ripoff.
I wish I would have known how much cheaper the newer coils are.

I have a 2000, stock motor, no bolt-ons. It had around 92k miles when I had a blinking CEL, multiple misfire.
2 of my coil packs (cyl 3 and 4 to be specific) went bad.
Not sure if these were the original coil packs with the motor or not since I bought the car second hand.
Replaced the two bad ones with coil packs from a TSX (K24A2 I believe?) and my car has been running fine, no CEL.
OPc, are you still looking for bad coil packs to dissect and inspect? I can send you the ones that went bad.

Great thread guys, interested to hear about testing results. I found some AP1 aftermarket coil packs for $18 shipped on eBay, but am a little hesitant to purchase them. After reading this thread I searched on the 04-05 coil packs and found an auction for genuine OEM Honda ones for just under $25 shipped. For that price I think I can afford to try those and see if it solves my idle issue (no CEL).

*edit*
purchased 4 and total with shipping was $86.29, less than 1 AP1 coil pack from hondaautomotiveparts.com.

To date, I have found 3 bad coil packs in 9 years of working on the car.
1 was in an AP1 with 140k.
Second one was an ap1 with 160k or so.
Third one was in the same car with 160k. So 2 packs in one car.
I have coils to disect if anyone wants them.

Looks like the coil winding is shorter. I wonder if they went with a smaller diameter wire, or a stronger magnet in the core? Could also be the FET/IGBT is faster. 
To add to Billman's list, my coil didn't fail until over 100k, and I had a plug back out which probably took it out much sooner.

Neat. If no one else wants it, I could take apart and photograph one of them (preferably an AP2 coil pack).

If the question is if it runs then yes it does. I have an ap1 MY 01 and just put some from a 2007 before I read this thread. I also have a cel for misfires. It runs BUT it feels like the car is driving worse than before and I still have the cel on.
