[DML] Re: Radio Interference

["daveswingle2" <swingle_dmc@xxxxxxxxxxx>]

Kind of snake-oily. They don't say how RFI is eliminated, and lowering the conductor resistance is not the way to do it. If you eliminate the resistance the RFI gets worse unless the wire is externally shielded. You can shield this stuff all you want, but if the shielding isn't visibly grounded somewhere it doesn't really doing anything other than emptying your wallet.

Someone once said to me "you can have "performance" (cough!) or a quiet radio. 

Resistance in plug wires is NOT a big deal in terms of ignition performance especially in an engine like this. At the voltages involved a few hundred ohms is insignificant, and the system will only run at the voltage required to jump the spark gap anyway. This car runs a pretty small gap and not particularly challenging cylinder pressures. 

As you might sense, I'm really annoyed by all the BS that goes on in the ignition parts business. It's 99% marketing crap. The funny thing is that you'll see this sort of discussion on almost every car forum of every brand, and it's all the same crap and you'll usually hear the same net result. On stock engines leave the ignition alone.
