COP system replacement coils
I went back to the Jegs site and found their part #40130 for 19.99ea. Since I have a 2v engine, I think it is a pretty good price, so I called. No one knows where they are manufactured, but they have a one year warranty, and for me, only 13 bucks shipping, I'll have them within 2 days. 12/28/11

Well, grabbed the TSB and all required tools and chemicals yesterday and attacked the plug change job. Followed the TSB to letter. After cracking them loose, precisely per the TSB, sprayed the carb cleaner in there and immediately saw the tiny bubbles coming up thru the carb cleaner and said, it's working like it should. Sweet.... Continued following the TSB like it was gospel and then attcked the 1st plug. 1st plug came out like it was greased and I was quite excited "this will work just fine and I saved alot of cash by doing this myself". Found out this was a teaser, like buying a lottery ticket and thinking of retiring to a far off tropical island surrounded by scantilly clad island women serving my every whim and desire. NOT
Epic FAIL.......
4 plugs broke and left just bottom part in the hole
3 plugs had the nut come off and left entire insulator in hole, intact. WTF?
At least the threads were all clean as a pin with no galling at all. The one plug that came out in tact had a gap of well over 0.080 (my biggest gauge wire) on it. May use some drill bits to see what it actually is. I believe the 100K plug change claim they made was tested in "perfect conditions" and an out and out lie used for marketing purposes.
Tried the Lisle tool to push the insulators into the sleeves and could not get even one to budge. Was in fear of pushing sleeve into the combustion chamber if I turned too hard. Could not get it to bite in even one sleeve to attempt extraction.
Sooooo, it's onto the flatbed and to the dealer she goes. Figuring I had been working on engines for 45 years and (including building Hemis for AA fuel cars) a spark plug change was well within my capabilities. Lesson learned for me, should have "driven to dealer" and paid the money up front for them to do it.
Am convinced that if plug is going to fail, it happens as soon as the wrench is turned 1/8 to 1/4 of a turn to "allow" the chemicals to wick down to the carbon crap to "loosen it up" and nothing can be done to change this. Once the damage is set in motion, nothing will bring it back from the doomed. If it comes out in one piece, then it wasn't going to break in the first place..
Cousin is service manager in a Ford dealership and stated that the official plug change interval had been changed from 100K miles to 60K miles on the effected engines. Something I had never heard before..... He also mentioned doing many engines after the owners tried this themselves and had seen the sleeves pushed down into the combustion chambers. Even had one where the owner pushed it all the way in and left it there, destroying the engine.
If I had been as keenly aware of this problem a while back, would have insisted dealer change all the plugs as a condition of purchasing truck last March. And will change plugs well before they have 50K on them from here on in.
If I had bought a Dodge instead, I believe changing the junk transmission would have been easier (and possibly cheaper) than changing 8 stinking spark plugs. ARGH........

People have had A LOT of luck running techron additive in their tanks for a few tanks before the plug change with very good results. More stories come in with successful changes, no breaks with this method. Hope the dealer don't clean you out.
All the coils sets I've purchased in the past from Global are GAMMA's. I've never had a problem with them. BUT, it's been awhile since my last purchase. From 05 - 09 they sold GAMMA's. I believe these are or WERE the good ones.

I'm not sure what's changed, but since quite a few seem to be having trouble with these cheap coils, I'll post what I've heard and found in the past. I spent a little time researching an alternative here and there and came up with this.
I've tried to tracking down the main supplier in the past. The trail got cold, ending at a manufacturer over seas, China. Although there isn't supporting data either way, it's hard to believe Visteon (Europe) and Motorcraft coils originate from same place.
From what I've heard in the past, Visteon coils haven't been failing from ebay suppliers. They're a little more expensive, most under $200 for a set.
So where does the trail end with Visteon coils ? -

Yea.
So, I'm sure not going to pay the Motorcraft price. I have a hunch where they come from, -just can't be positive so I won't post about that yet. Feel free to guess.
The best money spent may be on Visteon's at this point. Since Visteon is or has been an official Ford supplier in the past. Also, I would imagine Ford spec'ed these coils.
They're out there. -

I'm going to try a set as quite a few have in the past and reported good luck with them. You can visit the Ford Lincoln, Cadillac forums and search "Visteon Coils" for user data.
If anyone has solid information to add, feel free to do so.
Good Luck!

Have an "attempeted to use once" unused Lisle tool on the shelf now, just incase.
Must have done somethng right in a prior life. Dealer charged me 270 bucks to remove the 7 broken plugs and put it all back together. Back on the road for 330, including the tow.. WooHoo..... and she runs like a dream. Anxious to see what the gas milage / towing does now with the new plugs and to see if my 50+ mph, light throttle, intermittent miss is gone now.

04fxdwgi, you may have just scared me off from making my attempt. In am going to check the dealer for the cost of having them changed today. I love to work on my own rig, but if there is a better than average probability that I would end up at the dealer on a flatbed anyway, I would prefer to drive.
If I decide to still do this myself I plan on trying all the tricks to get it right. Although it sounds like there are plenty that fail epically doing just that
I will likely be changing the COPs at sometime in the near future as well so was glad to see the Visteon and Jegs as viable options.

It's really a wast of money to change COPs unless you have one after the other going bad all the time.
I still have the original COPs on my 2000 Grand Marquis 4.6 with out any problems.
Knock on wood..lol

I'm looking for some new COP's for my 2005 4.6 and found these on Amazon for $70.00 - for the set? Am I missing something here, or is it just one? If you scroll down just above where it lists the vehicles it fits it says "Brand New OEM Quality 8 Ignition Coils(Lifetime Warranty) Will Fit The Vehicles Below :"
http://www.amazon.com/Ignition-MOUNT.../dp/B0031ZDU62
If that is just for a single one, how about the Accel coils? They sell a whole set (8) for $165.00. Are these any good?

I would go with the cheap chinise made ones before I'd go accel. If you want good ones go to rock Auto and get the stock Motorcraft ones. If you buy the cheap chinise made ones get the 10 pack so you have spares when they fail.
I bought the Jegs coils for my '98 5.4, and it purrs like a kitten now. Haven't been able to check the mileage yet. Jegs even has a price matching policy, so
I got them for $17.99 ea. Made in China, but most of them are anyway. And I trust Jegs for warranty back-up. Or you could buy the Visteons from E-bay, I suppose, for the same price, but I couldn't find any warranty info, and they may be Chinese too! Ya pays yer money, and Ya takes yer chances!

The remaining Visteon coils were made at the Ypsilanti or Rawsonville plants in MI. When the 2011 F150's were launched, Visteon no longer made coils anywhere. I'm no longer the engineer on the program to know who the new supplier for the new engines are.
Note - Visteon never made coils to be sold on eBay (you might be getting fakes). Your best bet is to get them at the dealership.

Your kidding right? Stay away from any dealership you can! Unless you have money to burn.
Motorcrafts ? Yea, I can only speculate. The trail ends over seas, -for me anyway. Wish there was better data out there.
