What is the big difference between good plug wires & the ones that have "suppression" listed?

Is it the radio reception, or something else?

Thanks.

 

supression is for radio interferance, i ithnk all wires do that now, except flat out solid metal race wires.

 

Resistor wirea also deliver a single, hot, high current spark, instead of the multiple sinusoidal spark that can occur with solid wires. There are conflicting theories about which is better, but the LS6/Z06 'Vette that will leave you in smoke uses resistance wires.
