Coil Pack Problem
Coil Pack Problem
What is the best Coil pack to go with for the 5.4L? Been having a problem with them going out. I'm running a SCT Programmer, so I did know if this is cause the problem. She runs great with the tune I have, but when those coils start, it's starts running like crap.

Lots of people here just run those Global ones off ebay, I've got a couple on mine.
$85 shipped for 8
And depending on the year model, make sure you check or have checked the intake... I thought I Was just losing CP's but turns out my intake was cracked, leaking fluid down into my cylinders.

Good luck with those Accels, they have a pretty bad reputation.
People recently haven't been having very good luck with the Globals either.
The Visteons I linked are essentially OEM. Visteon is European Motorcraft.

The OEM coils are as good as your likely to find.
Quality has no measue, so far, against the OEM units. Don't use price as a quality measure.
.
The coils live in a harsh enviorment where they are mounted and cooling can be a problem from expansion and contraction due to the wide heat range they are subject to..
The engine bay heat can rise to 250 degrees for a number of minutes after shut down.
.
I would recommend for the total cost involved, that you consider mounting at least an 8" electric fan in front of the radiator and use an adjustable temperature control thermostat placed inside engine bay and set to about 185 to 190 degrees to come on so when you shut the motor off the engine bay is cooled down much faster and limits the highest temps to a lower value. The fan won't take much more than about 8 amps and for the run time and is not much on a good battery for that time interval.
Normally in ambient temps of 95 degrees, the time it takes to lower the engine bay from a shutdown is about 6 minutes+/- with the fan.
Wire the fan through a fuse to be powered full time except when the temp is below the thermostat setting it does not run making it automatic.
This saves on coil life and deterioration of rubber parts.
I have had this setup for over 130,000 of the truck's 170,000 mile life but cooling a trans cooler that is mounted in front of the radiator but get the additional benifit of engine bay cooling after shutdown. So far no rubber part failures but that's not to say they are perfect after all the time and age on them.
Good luck.
