What are these markings ? (2017 ram)

Looks like your mechanics made a great choice with the "Sultans of Spark" Hemi replacement ignition coils.

Nice improvement of
Consistent 40,000 volts vs
stock coils at 30 - 35,000 volts that drop off under load.

SOS coil users are saying better throttle response and better fuel mileage with the new replacement coils.

Able to open up the spark plug gaps to .065 ths with the higher voltage coils. Coils are wound with heavier gauge wire too for less resistance, and holding voltage under load.

All good information to know.

Thanks
