MSD Spark Plug Wires

Code: MSD31329

MSD 8.5mm Super Conductor spark plug wire sets feature a special helically wound core that has just 40-50 ohms of resistance per foot—but with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire includes 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference “choke.” This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle.
