So, they claim a 14HP boost just from installing their coils (peak HP +38 @4000rpm).

There was talk of this on F-150 Ecoboost forum, also Granatelli Motorsports had an extensive mods video with several incremental mods including their own "brand" of coil on caps, claiming even more hp than the "Sultan of Spark" brand.
The common denominator with both brands and their promo videos...zero mention of beginning mileage for the OEM parts.
Some folks drive a lot during the course of a year.
The sos truck was a .2016 model, which could easily have been on the road since late 2015.
Was the video made recently???
If it was in the last few months, that could indicate the truck has been accumulating mileage for 3 years.
Just saying, a true test that is more indicative of relative change (good or bad) would be with back to back testing with 100% NEW OEM coils vs the aftermarket coils.
The way both have chosen to publish the "improvements" they've found over OEM coils are suspect at best...IMO.
So the question then would be, if the aftermarket prove no worse than OEM, when directly compared to NEW OEM coils, are they as durable, and what of the price point versus OEM?
If a set of OEM coils are $300 and MSD, ACCEL, SOS, are $250 yet the OEM has 12 month 12,000 mile warranty...me thinks there's more value in the OEM parts.
