i haven't had any problems since i switched back to factory wires. the engine runs great. not sure what caused all the mags to die but i guess it could of been the plug wires arcing. just don't know. bought an auto condenser and installed it in one of the dead mags and that mag is working now. i do know the rf signal killed one of my wide band fuel ratio gauges and the other one would work off and on with auto plug wires. now with the shielded wires it works perfect.
