Worked as expected. Motorcraft coils brought back my smooth quiet idle on my 08' Navigator with 212k on the odometer. Always use OE parts for electrical units that report back to the ECU. I previously tried after-market coils and it impacted the ECU, which in turn made my transmission malfunction and throw codes. I have had the same experience with oxygen sensors. Stick with the OE part. Ford engineers have the car/truck and the corresponding ECU and electrical components mapped to OE parts. It's best to keep it that way. There are some parts which can be aftermarket but, I wont do it with electrical parts---

This "appears" to be a genuine Motorcraft part but it's not. The contact spring is a full half inch shorter than the original part and will not make consistent contact with the spark plug. I had to reuse a spring from the coil pack it replaced. I will not purchase this one again.
