Review on Ignition Coil Pack Set of 6 - Compatible with Ford, Mercury, Mazda & Lincoln Vehicles - 3.5L, 3.7L V6 - Edge, F150, Explorer, Mustang, Taurus X, MKZ - Replaces OEM Numbers: 7T4E-12A375-EE, DG520, 7T4Z12029E, DG-520 by Brandon Frogge

The average rating is not based on the quality of the product but on the original poor compatibility decision tree. I carefully entered all the necessary information for my car and the program said that it is suitable for my car. I don't know if the manufacturer or Revain is responsible for the compatibility program, but this time it failed. They probably fit the 3.5L non-turbo engine. The ribs on the coil connector just don't match perfectly and won't insert the connector no matter how hard you try. I tested with another coil in the pack and same result.
