MSD 8.5mm Super Conductor®
The MSD 8.5mm Super Conductor is the ultimate performance wire! Its extremely
low-resistance combined with the ability to suppress Electro Magnetic Interference is a
combination that defies the common laws of physics.

Less resistance means more energy is going to make it to the spark plug to ignite the
air/fuel mixture. The Super Conductor uses a copper alloy conductor resulting in less
than 50 ohms per foot of wire! This ensures that the most energy possible makes it to
the spark plug. By helically winding the conductor around a special core, we are able to
produce a highly effective choke to keep the EMI inside the wire and away from other

This combination is encased in a heavy duty sleeve that will withstand abrasion and
high temperatures. Cap off each end with our Dual Crimp Terminals and you have the best
wire available!

Copper alloy conductor has a resistance value of less than 50 ohms per foot for superior spark
Ferro-magnetic impregnated core creates an effective EMI choke
Forty feet of conductor is wound into a single foot of wire for high EMI suppression
Conductor core features Dupont Kevlar material for increased tensile strength
Durable outer sleeve is a proprietary compound for resistance to high heat or abrasion

The MSD’s 8.5mm spark plug terminals feature “Dual
Crimp” terminals. As the name implies, the terminals
feature two crimps; one for the sleeve of the wire and
another separate crimp to grasp the conductor.
By having separate crimps, the conductor doesn’t
need to be bent 180° and get squeezed between the
terminal and sleeve. This individual conductor crimp
produces a more secure crimp and there is less
chance of spark arcing to the engine block or exhaust
manifold through the boot!
