Again !!

My 03 5.4 Super Duty goes through ignition coils like crazy. It has about 170,000 miles on it and I've replaced at least 5 coils. I'm thinking of replacing the whole set with MSD or Accel, and installing them with dilectric gel on the boots to keep out contaminants which aren't doing the coils any good. The MSD and Accel coils are much cheaper than OEM and might last longer. Any thoughts or opinions would be appreciated !

You always want to use dielectric compound. Plugs will destroy coils, so, what kind are you using?

I changed out #7 today with a new borg warner. It came with a lifetime warranty. ORiley only had dielctric gel in tiny contaners so I didn't use it. This weekend I'm going to remove clean and seal with gel all 8 coils. Any thoughts on sealing the tops of the boots with the gel?

You are replacing the boots with the coils, right?

If the boots are new you really shouldn't need to seal them with anything.
