Forgive me if this has been answered a million times. I did a search and couldn't find specifically what I wanted. What I need to know is how difficult it is to replace a coil pack on a '97 5.4L. I twice paid over $300(including the coil) to have one installed at the local Ford dealership. I now have another one bad and want to do it myself. I can get one for about $50 at AutoZone, but I wonder about the quality. Would I be better served to get one at the dealership? Thanks in advance.

 

I have installed 3 of the coils from Autozone and or Advanced Auto.

The Sorensen coils I have installed on my 5.4 work just as well as the high dollar MotorCraft ones did or do.

I am not hardcore keep it motorcraft for the reason if motorcraft was indeed the best it would probably have a service life of over 20,000 miles which seems to be about the mileage on a coil before one sees some failure.

IMHO

Thanks Tom! How tough are they to install?

 

autozone also sells Borg Warner coils...four screws keep the wires in order..how old are your plugs,wires?...think you may be chasing a ghost?...check you PCV line behind the throttle body

 

On the 5.4 replacing the COP coil assembly is a matter of unplugging the wire and removing the 7mm bolt that secures the coil to the air plenum.

The only one I view as difficult to remove is number 7 due to it's location and the fuel rail's location. a 1/4 inc swivel will be needed in addition to the 7mm socket to remove this one easily.
