[QUOTE="JMichael, post: 397198, member: 7544"] Yes the R indicates it is a resistor plug. Resistor plugs, just like spark plug boots/caps, and resistor wires, have resistance built in to them, and were designed to eliminate RF (radio frequency) noise. RF noise use to be a big deal back when we only had AM radios. Now days (as far as I know), the only good reason for running them is to eliminate possible RF interference with sensitive electronics, although those electronics would have to be pretty close to the source of the RF noise in order to cause any issues. If you inadvertently install multiple resistor items in an ignition system like resistor wires and resistor plugs or boots, you could potentially weaken the power to the spark plug and cause a weak spark. But to answer your question about damaging your coils, I've never heard of that happening or being a possibility, but since we're all human, and subject to making mistakes, I won't say it's impossible to damage the coil if you install too much resistance in the ign system.
