Are the coils for a 5.4 the same as 6.8? MSD makes coils for the 5.4 but no info on the 6.8. Also was wondering why the Granatelli Motor Sport coil packs are 525.00. Is there a major difference in any of the major brands?
Note to OP:
Several folks have reported disappointment in the reliability of aftermarket COP's in comparison to the OE Motorcrafts. Do your research before dropping the cash.
Most have been able to find OE Motorcrafts for under $50 each with a few minutes of research.
