Ignition coil sugestion 97 Expedition 5.4
I see a set of 8 on Ebay from CBS Automotive Group. Anybody use these? I also see some good pricing on Rock Auto, which vary in price for some reason as they "look" all alike. I have used Rock Auto before for parts.
Also any preference on spark plugs?
Thanks, TLR

I installed these on my 97 5.4 and it's been running great ever since.
Set of 8 - $105.00, free shipping.

Plugs
I got my plugs on ebay from marketingdepot.
They work great and you can't beat the price!

I got my coils from the same seller as alloro, but haven't needed to replace them, yet. Just an awesome deal, not worth passing up.

Chances are you do not need the coil packs just the boots for the coils which can be purchased at NAPA. If you reply to me, I will be notified of your reply and I have a posting at work on how to test the coil packs which was posted on this forum a few years ago. As far as plugs go, stick to the Motorcraft.

Our new Ford COP’s, the Sultans of Spark(S.O.S.), have
been designed with both durability and performance in mind.
Please see them at:

Quality was the main feature we stressed when we went to the
drawing board on these coils.

Lightning Force Performance has a set of 8 accel coils, a fuel filter and 8 plugs(not useful unless s/c'd) for $239. the coils and fuel filter are the same as an N/A engine. i may go that route myself.

$339.00 for a set of 8, plus another $16.00 for S&H?
I bought a set of 8 for $105.00 with free shipping. I could buy 3 sets (24 COPs) of the ones I got for a total of $315.00 and it would still be $40.00 less than what it costs to buy one set from you. IMO, you've got no bragging rights with a "bargain" like that.

Maybe SOS one are better maybe they're not, maybe they increase horsepower maybe they don't. There was no test data posted to back up their claim of running 0.84 seconds less in a 0-60 time trial. Was the same truck used in all the tests, the same driver, same day, same weather, etc.? Then there's two items mentioned that raise a red flag. One being the increase from 25K to 40K volts, giving you a hotter spark. This alone is enough to fry your plugs. But to compensate for that, it is suggested to increase the plug gap. This increased gap in turn reduces the temperature of the spark, so what is the real gain if any?
But just for arguments sake I'll give them the benefit of the doubt and say there is a hotter spark creating hotter combustion. This brings up a second point, hotter combustion will require a higher octane gas to avoid the preignition associated with higher combustion temperatures. The cost of the higher octane fuel offsets any HP/MPG improvements you might have gotten. Of course you could stick with 87 octane, but as preignition is detected by the computer, it will compensate by retarding the timing and your power drops off yet again.
Like I said, maybe they're better, but I need more than, "because we said so" before I believe it.

Yes, our tests are always tested back to back, in a professional manner.
A more intense spark allows you to open up your plug gaps wider, burning a higher percentage of you fuel mixture, hence more power. But, you do have to have an ignition system which is strong enough to jump the wider gaps-which the S.O.S. Coils are.
You CAN run 87 octane with no problems.
