Coil Replacement - Best Value
I'm getting ready to do coils on my 06 F150 5.4 3V. I see some mixed reviews on amazon. I did a search to see if there is already a thread on this and it didn't jump out at me. I see 3 main options
1. Cheap Amazon - DG511 equivalent - approx $70 for 8
2. Accel 140033-8 - Approximately $210 for 8
3. Motorcraft DG511 - Approximately $450 for 8.
there are others out there too...
Any long term reports on the Cheap Amazon ones, I see some negative reviews but you can alway find some negative reviews even on a good product...

For value I would think replacing one at a time as they fail with Motorcraft would be the best bet. At 140k all the coils on my truck still appear to be factory. I have had it since 90k and have not had to replace one yet.

I agree with cb13. I preemptively replaced all of mine, when I was not having and issue persay, and ended up having all kinds of problems. I purchased Motorcraft coils from Summit (~$40 each). What I eventually figured out after individually replacing the replacement coils was that I was receiving two different versions of the coil. They all arrived in MC boxes marked DG511, however some of the coils had a different Ford engineering number on them, and they caused problems after a period of running fine. In the end, I put the original coils back in and all is good. I have 161k mile now. BTW, Summit was very good about warranty replacements.

Have the plugs been replaced? Were they replaced with motorcraft? There seems to be way more plug than coil related problems with these trucks. Some have experienced issues with non motorcraft plugs as well.

My truck had a hesitation / miss fire problems at 100K km. At first I taught it was transmission stutter problem. Did the flush but problem presisted or even gotten worse by the week. Replaced all spark plugs (sp515) and all problems gone. The mechanic checked all coils and they were good. He also said if the coil fails, it will fail suddenly and missing a cyclinder is a big shake. I will not miss the vibration.
It is not common to have all 8 coils failed at the same time, it is cheaper to replace just the bad one(s) with OEM parts. They are easy to be replaced anyway.
