The MSD 8.5mm Super Conductor Wire is "the" performance wire.Engineered from the inside out, the 8.5 offers everything you have everwanted 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 it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears.

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.

  • Racers never stop experimenting as they search for every way to wring out more power or handling performance to to gain an edge over the competition. The team at MSD is no different as we strive to deliver the products you need to meet your performance goals. We continue to innovate and invent components and technology that deliver performance and reliability with products that are easy to use and install. Over the course of 40-plus years, MSD Performance has been driving the development of innovative components that helped shape the way our cars race and perform. From super speedways to road courses, land speed racing to top fuel dragsters, and of course your traditional hot rod, MSD has provided the components to fire nearly anything in motorsports. MSD was the first company to develop and offer the multiple sparking, capacitive discharge ignition for engines. The line of MSD 6-Series Ignitions are the most popular aftermarket ignitions in the world due to our race-proven performance on the track and our reliability on the street! Early on, MSD focused squarely on ignition systems with revolutionary products like the multiple sparking CD ignition, timing and rev controls, billet aluminum distributors and the Pro-Mag, an incredible breakthrough in power and endurance. Today MSD is developing electronics for your entire powertrain. The Atomic EFI systems for the LS engine platform and throttle body are now complemented with a transmission controller. Our DynaForce Starters and Alternators ensure that your engine cranks over to fire up and the Alternators keep it charged. MSD is poised to deliver components that work and communicate together to provide performance and value.
