MSD's Super Conductor Spark Plug Wire Set is engineered from the inside out to deliver extremely low resistance without electronic interference. A single 12-inch length of Super Conductor wire carries only 40-50 ohms of resistance — the lowest of any helically wound plug wire — thanks to a copper alloy conductor wound tightly around a ferro-magnetic impregnated center core. This construction produces an effective Electromagnetic Interference (EMI) choke that keeps interference contained within the wire, while a silicone and synthetic outer sleeve resists high heat, abrasion, and tears. Each 8.5mm terminal uses a Dual Crimp design, with one crimp securing the wire's outer sleeve and a separate crimp grasping the conductor for a lasting connection.

FAQ
What vehicles does this wire set fit?
This set is a custom, precut fit for 1990-1997 Chevrolet and GMC C/K1500-3500 trucks, Suburbans, and full-size vans equipped with a big block V8 and EFI, plus select GMC/Chevrolet Express/Savana 3500 vans.
What is the wire diameter and resistance rating?
This set uses MSD's 8.5mm Super Conductor wire, rated at only 40-50 ohms of resistance per 12-inch length, among the lowest resistance of any helically wound spark plug wire.
What terminal style does this set use?
The 8.5mm spark plug terminals use a Dual Crimp design — one crimp secures the wire's outer sleeve and a second, separate crimp grasps the conductor.
Does this wire set help reduce electronic interference?
Yes. The tightly wound conductor and ferro-magnetic impregnated center core create an effective EMI choke that contains interference within the wire rather than letting it reach other vehicle electronics.
Is this set precut, or do I need to trim the wires to length?
The wires are precut to exact specifications and custom fit for the listed make and model, so no cutting is required for installation.
