These ignition coils are crucial part of your ignition system. Their function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time. This will cause a misfire condition. In engines like this with one coil per cylinder you can diagnose a coil by putting a timing light on each one to make sure it is lighting the light consistently.

Bought a Lincoln continental. The parts fit perfectly the car runs fantastic. I will always order my parts from you all. Glad I got the right parts the first time. But I paid for 2-3 day shipping so I could have them here for our weekend away and they did not get here for almost 7 days came at 7 pm on the 6th day. Guess it doesn't pay to have them expedited to get here quicker very disappointed in that so if not in a hurry then this is the way to go.

Didn't work on the 5.4 L motor cause the motor and vin didn't match With A Vin not the same as engine :;
The coils were to fit but didn't cause the 8th digit was an A but he Engine was an upgraded engine put in this vehicle still a 5.4L but runs only when going 50 + and dies when idling . Could some one have know the difference in the two being a different fit for this upgraded engine .....?????

Now after spending lots of labor time changing out the 8 plugs and these coils the problem is worse had I left it running on 6 coils
