Coil pack ?'s
I was looking to upgrade my coil packs on my V-10 X having 127K on the clock I'm guessing its getting about time to change them anyhow.........I had looked at the MSD coil packs and WAS going to purcahse them BUT a friend of mine installed the MSD's on his 04 4.6 mustang with ONLY 55K on the clock 2 weeks later the motor let go after loosing the head gasket on the DR. side bank....Kinda makes me a little uneasy performing the swap..............The question is has ANYONE used these coil packs or know of anything I can use that is similar??
Thanks
John

^^^Agreed. Modern coil on plug technology has come a long way. You no longer have one coil firing 8 or 10 cylinders and struggling to recharge itself between firing with inferior internal components. Each one of those coils makes more power then most aftermarket performance coils of just a few years back.

You cannot beat the OEM COP's. Most of the high power Lightning trucks still use the OEM coils because the MSD's and Granatelli's have proven to be lacking when compared to OEM coils.
About the only aftermarket COP any of my Gen 2 Lightning brethren have had consistent luck with is the Weapon X coils.
All you'll ever need is the stock coil for your rig.

I'll reitterate what others have said already. The stock coils are plenty good. They've lasted you this long, right? I had some aftermarket coils on my Town Car when I had that. Not only did they not last, but after about 2 months of them being installed, the car started having running issues that it took me months to track down. Finally, someone suggested it might be the brand new aftermarket coils I'd installed. I ripped the coils off of a 4.6 I had in the basement that had survived an engine fire. Put them on, car started right up and ran great. No problems for the remaining year and 10,000 miles I drove it.
Ford put these factory coils through lots of testing when they made them. I know because I'm friends with the guy who headed that program. Obviously the coils aren't perfect, but if nothing else the R&D that they did is more than any of the aftermarket companies have or could perform. One thing my friend told me is that they did experiments with higher voltage coils, and all they found was that the higher voltage coils would break significantly faster with no worthwhile. I can say from my experience that he was right, he was the one who told me to rip off the aftermarket coils.

Your initial post, in different wording, stated you were looking at replacing the COP's for preventive maintenance only. Which ones are bad?
Eh, actually, it doesn't matter. If it were my rig, I'd only replace them as necessary.

I replaced all 10 on my truck. Why do you want to deal with the hassle of replacing one or two at a time? They're all going to go bad. In my case on my truck, when I bought it the previous owner had let it deteriorate to the point where 8 of the coils were bad. That decision was easier. Still, I think most people are doing a false economy by only replacing the one or two bad ones.
I bought mine from one of the Ford parts warehouses on the internet, I can't remember which one. Probably genuine-ford-parts.com, I've used them a bunch of times before. There are several and their prices are all slightly different.

I made the swap on our mustang to the Accel COPS and in 3 months we had one fail and the car ran like crap. It was pretty obvious one had failed as it missed and sounded like a train chugging. Put the stockers back in the car that had 95k miles on them and it ran perfect again. I sent these Accel back in and they tested them and found that the pack indeed failed. They sent back to me 8 new COPS that I have sitting on a shelf in my basement. I will not put them back in my car or on the X. If somebody wants them, PM me and I'll give you a great deal on them.

What do these typically go for ???
Just did a quick search here in Canada at they run around $85.00 each!!!! That's quite the bill to change all 10.!
What are the average prices in the States?

If you have a miss and the ECM doesn't set a code, do the following;
You don't need to change all 10 COPs if your truck misses and you get no CEL. Buy one new unit and put it on whatever cylinder you want to start at. I usually start on the hardest one which is #5 (it's usually the one thats bad since its shrouded and gets the hottest). Put the new coil on (#5) and drive the truck. If the miss goes away, You're good. If not, the COP you have taken off the engine is now a "known" good COP. Move that COP to the next one in front of #5 and so on and so on until your miss is gone.
This is about the only way you can find a bad COP without a CEL, unless of course you have a Rotunda breakout box, and if you can afford that, you don't need to mess with this problem at all.
I have replaced 7 COPs on my truck since '99. In my experience, the best quality aftermarket ones are the NAPA brand COPs. They actually look like they are manufactured better than the motorcraft units.

I say just replace what you need and keep a spare in the glove box with teh tools you need to replace it. Its very easy to diagnose a bad one, and they swap in a couple minutes. Or if you need to save $ replace what you need now and when the next one dies replace that one. As long as you dont drive around long with a dead one you'll be fine. Driving for a while on a bad one will "wash the cylinder down" meaning wash the oil off the cylinder walla nd wear the hell out of it as the rings go scraping by with no oil.
