can I use this coil as is?

Uh. no it is not

The user manual says you can omit the resistor when using with MSD IGNITION, which is capacitive discharge and works completely different from your Mopar ECU

Your Mopar ECU is "more like" points ignition than anything else, IE the Mopar ECU simply switches the coil in place of the points. Proper coil resistance/ ballast is important with these systems

MSD shows the primary resistance of that thing is only .7 ohms, about half that of a factory Mopar coil

As you can read resistor is for points system. You dont need it with 4 pin Mopar ecu. Ecu can easily deal with high current what 0.7 ohm coil gives. it work without resistor for me and it work for without resistor for everyone.
