So everyone is saying that by using a Resistor plug like the autolite r103 can short out a coil?

There are two sides to this excellent discussion - one side believes the use of resistor plugs can damage coils and ignition systems, while the other side believes the use of resistor plugs is acceptable. Also, this is not a one-size-fits-all sort of discussion; meaning there may be certain special mitigating circumstances in a particular model/year.

However, without additional conclusive and objective data from MB Engineering, we are sort of at an impasse and have to approach the subject with theory, personal experience and gut-feel. Therefore, you must use your own judgment based upon what you learn as to whether resistor plugs will work in your vehicle. Personally, I’ve enjoyed this thread immensely.

Cheers,
Jeff
