I took out my coild packs to inspect them and clean the connections and to apply the dialectric grease. When removing the boot there is a spring inside but inside the spring is some kind of rod. It kinda looks like carbon or somthing.

Is this a resistor? What does it do exactly? why is it in there?

I think its just to make a solid connection but I'm not 100% sure.

If you get new boots, you get a replacement, and yes that's what makes the connection between the coil and the plug. New boots cost $5-8 each.
Why would you replace em? does that rod thing go bad after a while? Mine had some white stuff on the ends of the springs but it cleaned right off.

I thought maybe if it was a resistor block of some kind we could maybe sand em down a little and increase the spark a little? If they are maybe designed to be a certin length? resistance?

When i first seen em i thought it did something to keep noise down. I remember in the spark plug wire days they sold plug wires with fiber in them to keep engine noise down on the radio and amp.
