FM Static after new wires installed.

The way I remember it, it goes like this;
The standard wires in many cars are not made of "wire" at all. They are made of a sort of a conductive, carbon string like thing. Since the spark is high voltage and low current, this carbon conductor works well enough to bring the high voltage to the plug. The idea was add some resistance to kind of round off the edges of the spark pulse waveform. If you round it off you don't get so many harmonics. Harmonics are signals that are produced at regular intervals up and down the frequency spectrum when ever you quickly start and stop a current flowing through a conductor. They used to call this suppressor wire. Some plugs had a resistor in them for the same reason. Those plugs had numbers ending in "R". If you put in performance wires that are made of real wire, you may produce harmonics that you can hear on your radio. A filter might help if the noise is coming thru the power wires. I don't think you will have much luck filtering out harmonics that are in the FM band and entering thru the antenna. All this may be old technology but that's the way I remember it.
What did you do to your Viper to make it need the new wires?

Unfotunatley in my experience, your going to have to live with that. You can purchase a filter at your car audio store in your area. They do help, but some noise still might be there...

I have installed the Mopar and MSD wires in my snake. The MSD wires have less noise than Mopar's

I'll just have to quote myself again;
"Every time you do something to your car you take a chance on screwing something up"
Don't fix it if it ain't broke.
I can see the flames in the distance from the torches of the town folk as the march up to stick me with their pitchforks.
