coil help please

[mercury5]

i noticed the numbers in each coil, my question is , when you buy replacement coil , the same kind do you need to look for the number under the new coil. and replace them that way

[babbage]

All 8 coil on plug units (cops) are the same.

Depending on mileage you should replace all 8.

Mine has 114K, probably original coils. How long do they typically last?

[Blk Mamba]

About 80,xxx miles.

[tbone]

Maybe I'm lucky, or maybe they were replaced. I bought the car at 92K. Is there a difference between what the factory installed and replacements?

[ctrlraven]

Got a p/n for new ones? I should probably go ahead and replace mine.

[Blk Mamba]

I bought the Accels, from Summit Racing, I think $27 @.

To answer you question they're quit a few part numbers to coils that will work on our motors. You want the Ford numbers, the Motorcraft numbers?, or the Mercury number's?

[tbone]

At that price, I'll wait until they fail.

See post. Thanks though.:beer:

[justbob]

Mine were TOAST at 65,000 if that helps anyone.

Almost 220K miles on my originals...gonna change them out next plug change but as far as I know they are still fine!!:beer::bows:

BTW, the last 135K miles were supercharged!!:D Cannot imagine why folks have so many coil problems unless to OEM connectors are the culprit.....I've had GMS connectors for around 175K miles!!!:bows:

I have 146-147k on mine. I did a plug change about 10k miles ago.

[fastblackmerc]

Definitely go with the OEM coils and the GMS or similar connectors.

[musclemerc]

+1 this has been my combination and so far they are trouble free

How in the F did you come up with this hairbrain conclusion OEM coils last 80k?

This site is continuing to suck donkey d!ck

It's not the site...

It's the misinformed.

In other words "if you don't know what your talking about..... STFU!"

[justbob]

Coils are like anything else...Some fail early, some remain fine. Mine went without any warning at all. The car would just hesitate, shake and shutter at anything over 4000. Could have been just one or two or even the connectors??? I don't like to play guessing games myself so I replaced all eight and had full power again. They cost me less to buy all new motorcraft than to have the old ones tested.... I have the old ones on hand that I will gladly let someone test out.

[4play]

170000 miles on mine still runs awesome

[Bobmiddle]

At 96k had 3 go bad confirmed by isolating each coil on a scan tool. Then about 3k miles late problem came back scanned again two more were going ban so I just replaced the other 5.

This site is continuing to suck donkey d!ckIf you think this site and it's owners suck so badly, why do you hang out here?

[Ktorres1]

I'm having more coils problems so I'm looking to replace the last three left.

Then maybe you should leave if you hate it so much

[ctrlraven]

Anyone have the part numbers?

[Ktorres1]

I don't, I've just been going one by one out of auto parts.

[musclemerc]

When I get home this weekend I will post this info for you

[SWOOSH]

Wowzer!!! Now that sounds like a deal!

[BLACKMARAUDER04]

Thanks for the part number. Those are described as ignition coils. What about the connectors?

I think it's safe to say, they are all one unit.

[BLACKMARAUDER04]

If they are all one pirece, why do some people have Granitelli connectors?

[Blackmobile]

Because some believe they work better than the stock connectors.
