Looking to possibly upgrade the coil packs on my 2013 Ecoboost. Your opinion on staying OE or going after-market? I know that MSD and Accel are now the same company.

Stick with motorcraft stuff. Also, make sure you are changing your spark plugs every 30k miles with motorcraft sp534 gapped to .030. Also, drill the 1/16" intercooler weep hole. You will never have misfire ever again.

There is no upgrade. As said above, stick with Ford ignition parts.

Denso coils look like motorcraft's, I know MSD has some that are alittle cheaper that a few guys are running, with no issues yet.

My #3 coil went bad a weekago along with my Throttle body, both replaced with OEM by ford under extended warranty. I have a 2011 Eco, FX4 only 61k. I know OEM Coils are the way to go but saw some place a guy was running MSDs and getting better gas milage, i've gotten about 13.5mpg since i've got the truck new

what benefit of upgrading a coil will you gain? not exactly an upgradable part...

Hasn't been any benefit of upgrading ignition coils on a Ford engine since they introduced TFI, unless you just wanted a different color coil. I bought a Ford Motorsport one once upon a time for a Mustang I used to own and grabbed my meter to compare the two. The difference in resistance between the two was negligible, and probably could have been chalked up to the age of the factory one.

I bought a replacement coil from Carquest. I compared the new unit from Carquest to the original coil I was replacing. They looked identical in every way. The only difference: There was light machining/grinding in the locations that the factory coil had the motorcraft part numbers printed/etched. I believe it is the same as a factory coil.

If/when I need another coil I will buy from Carquest again (or equivalent as the Carquest in town just shut down) and enjoy the savings. i paid a bit under $60

Thanks for the responses. I'm a bit old school and back in the day we would squeeze out a few more horses by converting from points (remember them) to solid state, then to a stronger coil for a hotter spark. I guess with computers it takes that out of the equation.

Once they eliminated the distributor, engineers were able to increase the voltage and duration of the spark since you didn't have the mechanical contacts to worry about any longer. Sure, folks have to replace these coils occasionally, but they're still much more reliable and maintenance free than an old dizzy setup.
