1997 Ford Expedition Ignition Coils

 

The 1997 Ford Expedition came with 2 different V8 engines, and these engines used two different style of ignition coils. The 4.6L V8 of this generation used two coil packs that were connected to spark plug wires. The 5.4L V8 used individual coil on plugs. Keep this in mind when ordering. Many people get this confused. When the ignition coils in the V8 began to fail, they tend to go out within a short time frame from one another. This is especially true when they are older. You can get away with replacing just one ignition coil if the others have been replaced recently, but when they are around the 7 year old mark, it's best to just change the full set. The ignition coil used in the 5.4L Expedition for the 1997 model year was a common problem. So common that the number one selling ignition coil in the country is the coils for the 1997 Expedition 5.4L V8 (DG508). Don't lose confidence in  your Expedition just yet. They have been around for long enough for aftermarket suppliers to lower the cost of the parts.
