This ignition coil is a FORD original equipment part! It is the same part that you would receive if you purchased it from your local Ford dealer!

The ignition coil is a crucial part of your ignition system. It's 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.
