MASSet of 10 Performance Ignition Coils Pack & OEM Motorcraft Spark Plugs SP509 Compatible with Ford F250 F350 F450 F550 Super Duty F650 F750 F53 F59 6.8L V10 Replacement for 8L3Z-12029-A C1659 DG521

Now installed and over 5000 miles completed. i like that the spark plugs are Motocraft, original equipment. the coils are very good and much cheaper than the OEM options. very easy to change out all plugs, but buy a plug wrench from Amazon for the job.Update: We purchased these coils in January 2019, we are now in July 2020 and i have lost two coils thus far.if you have a diagnostic tool you can easily diagnose which coil has gone. this was no. 5 on a V8. and it is not a hard job to change the coil, but how much damage am i doing to the engine and Cat. I was 5 miles away from the house, it took 10 minutes to identify the issue and install a new one. I purchased 10 coils and plugs for my V8, i have now used my two spares.

These did not work. Tried to save some money and these were an epic fail. We ended up having to modify these to make them work. Not worth the hassle forsure.

The product received is Motorcraft brand, Worked perfect in Ford Expedition 20105.4 3 V motor- improved performance

These were stated as OEM parts. The plugs were OEM, but the coils were not. The way it was worded was not clear and very misleading. We did return and purchase the Ford branded parts from another seller.

The one year warranty is substandard. These coils lasted two years. Other manufacturers offer a lifetime warranty and cost no more. I would rate at 0 stars if possible.

Easy to install so far works great solved the problem.

3 coil packs failed within 5 days. Trashed the resr and went with OEM.

These coil packs suck I have had 2 go out with in 2 weeks after installing them I do not recommend these at all
