MSD : 31229 : Spark Plug Wire Set - 8.5 MM - Super Conductor - Universal - Two-in-One - 8 Cyl - 90 degree boots and terminals plug / HEI cap - Red

The MSD 8.5mm Super Conductor Wire is "the" performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 12 inch length of Super Conductor Wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to its great voltage carrying capabilities.
  • For engines with late model HEI distributors caps. (Ford Duraspark or MSD Cap-a-Dapt) 90 degree spark plug boots installed with 90 degree distributor boots and terminals included.
