[RFI] Ignition Noise

[kate]

Recently I tried shielding my ignition cables in a Toyota 4 cylndr car to
suppress mobile ignition noise.  The cables were new.  While the shielding
helped significantly in reducing the noise radiation, within a week the
cables started breaking down and caused the engine to miss.  Obviously good
cables are in order.  Can anyone recommend a good manufacturer of resistance
ignition cables?  What about RG8, with a resistor to limit current current,
as an alternative.  Anyone have experience in this area? Thanks,  Bob
