Stick with the OEM, Motorcraft. Had 4 fail before the 15th birthday. Replaced all with Motorcraft, no misfire since. 11+ years from the OEM with a valve cover leak before first misfire, I can't complain.
Wow! That's great! Are there certain models of motor craft that are better?
I'm doing some more research. Will I need an ignition coil unit to go with the coils?
the coils are the "ignition COIL units"
you will need 8 coils and 8 spark plugs, and when you remove the current coils, if you find any oil in the wells, then you will also need VCGs
If you find one that last as long under the same or worse conditions, go ahead and recommend it.
I came out of winter 3 years ago with a VCG leak and misfire. Had VCGs and one coil replaced. Good for that year. Had a second COP fail in a year or 2, had it replaced, good for the year. Had 2 fail this year, had the remainder replaced, no more misfired for 4k mi so far. Would be nice if they lasted forever but they don't.
so what part numbers of Motorcraft coils are best? or are all Motorcraft OK?
Seriously?
DG529 is the latest revisions you could get for the the OEM coils your LS needs.
You would have noted that in the 100+ other coil threads.
Guess I will tag every post that comes up like this with an update. Delphis going strong, year and a quarter now. 7 k miles. It's looking good, need any new ones yet Joe?
