03 Big Red
True Believer
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 !
