question about spark

[STUGOTS]

Guys I have a small problem, I am going to Chucks on saturday to get a few upgrades done one of which is the MSD wires and Chuck told me that they may cause static in the radio and also cds,so my problem is this I bought a dvd player for the car and gave my old radio (not stock one) to a friend, come to find out the dvd player (bought on the net) was defective so I had to send it back and it WILL NOT be here by the time i have the appointment with Chuck so I have no way to test if the wires give me static or not.

So my 2 questions are...

1.how often does this happen (the static)?
2.does it effect after market speakers and head units and amps or just stock ones?


Thanks guys

You can get filters at Radio Shack that will eliminate the interference.

I haven't heard that the noise can be eliminated with filters.

The wires will not give you any performance increase, not even a little. They do look cool.

 

[STUGOTS]

im only getting them for look.

Joe is there a chance that they will not give me static considering the player is after market?

The problem is that with solid conductor wires you get a very sharp edge on the spark pulse.

When this happens, signals are generated that cover many frequency bands. These are called harmonics. Since the signals are real radio frequency signals, they may get into your radio in the same way that the radio station signals get in, through the antenna.

There isn't any filtering that will prevent this.

The sharp edges I'm talking about have nothing to do with the timing. They are a thousand times sharper, or you could say faster, than it would take to have an effect on the engine.

Sometimes an electrical device will generate electronic pulses that come into your radio or CD player through the DC power line. Those signals can be filtered out by an inline choke coil and a capacitor to ground. This is not the case if the signals are harmonic RF signals that enter through the antenna.

Resistor wires or resistor plugs round off the sharp edges of the spark pulses and prevent the harmonics.
Solid wires with resistor plugs may do the job.

My advice is this,
If the radio or CD player are a big deal to you, you should talk with people who have exactly the same solid wires and ask if they have been able to fix the problem to the point where they can live with it.

I've had the MSD wires for a loooonnnggg time and haven't noticed any static in my Gen 1. I have mostly stock speakers and an aftermarket low budget Kenwood 4-channel amp (because one of the OEM amps died and it was cheaper to get a 4-channel than a replacement OEM amp.)

I've got MSD wires and have no static at all.

The MSD Super conductor wires (that we use) are not solid core. They are low resistance, high EMI suppression wires. I've never had any static with them, but have with other brands (on a Viper).
