COP'S From Ebay
 

Hey, my 06 had a misfire, I'm at 89k So I decided just to change the coils and I would change my plugs at 100k. I bought my coils off ebay from reading good feed back on here. The truck runs like new again! Wow what a difference it made by replacing the coils, I can't wait in till I change the plugs. I'll posted a link where I bought my parts if any one wants it.

Do not throw away your real OEM motorcraft coils. I did the same thing you did almost two years ago on my 2004 5.4. I bought could off of eBay from either uneek or global, I don't remember which. It was the common wisdom, just replace them all with these eBay coils.

The eBay coils are not the same quality as the motorcraft coils. They will start failing one by one in à year or two from now.

My advice is that if you have a miss, order a real motorcraft coil from amazon for $45 and replace it. The dealer wants $70+ for one.

How to find out which coil is missing? If it sets a code you can go to auto zone and they will pull the code and tell you which cylinder is missing for free.

I use a Bluetooth obdii reader that I bought off of Amazon for $20. It works with the android app called "torque pro" that costs $5. It will not only read your codes but it will show you real-time engine cylinder miss counts. You cannot do this with the free version, you must spend the $5 and get the pro version.

With torque pro and the obdii Bluetooth interface I can see exactly which cylinder is missing. Then I buy the coil and replace it easily, no other troubleshooting necessary.

I threw away my OEM coils, wish I still had them.

Ebay/Amazon coils are one the best, - if not The Best suppliers out there. If you listened properly you would have known WHICH coils to purchase. Those aren't recommended here, - they are buy at your risk coils. Best coils for these trucks are Visteon/Motorcraft and that's what's been recommended for years.

Good job with the torque Pro app, yea that's old news, -but it's definitely a great app to have.

When you have an engine problem, try searching the "Engine" Forum, -it's all there. Shoot, it's been there for quite awhile now. :thumbsup:

BTW, - They are VERY cheap if you know where to go.

Thanks! I think you might have missed the part in my post that I bought my coils two years ago. At that time uneek and global were the recommended eBay suppliers on this board. I read hundreds of posts in this forum and in the engine forum on this subject.

Regarding the motorcraft coils on eBay for $189, I am guessing they are fake. It is a huge business making take oem parts, Ford logos and all. I am a designer at Ford and we take classes training every few years on this exact subject. If they came in the original motorcraft packaging it might be a different story. It would be interesting to compare mold marks and the innards.

Going to stick with my amazon genuine motorcraft ones for now

Thanks again.

The genuine Motorcraft coils are paint marked at the factory. I've never seen anyone try to copy that.

If you work for Ford then you might know Visteon's are spec'ed the same as Motorcraft, - Identical w/0 failures. Those are what to get when available. Problem is, they go fast and suppliers run out. Well, they run out of the 3 valve coils anyway. Yea the other cheap Ebay coils only have single wire build magnets and can't survive thermal shock levels like the Ford spec'ed coils. One little surge and they could be toast lol.

Visteon isn't here in the states anymore, but their coils are still produced in Europe; -Hungary to be exact.

I will save up to buy the OEM coils from amazon may be in a couple months.

Last I heard, MSD COPs were still junk. Any change to that? Also, are Taylor Thunderbolt COPs worth looking at, or is Motorcraft still the only real option?

Thanks.

Check out the Visteons I linked. Same as Motorcraft.

Sorry if I'm jacking the thread here but I'd rather ask yall than make a new one and yall seem to know your stuff. Can you explain what coils are and their function? What does replacing them do?
