MSD Ignition – Wire Set; Super Conductor; Small Block Chevy with HEI Cap (Part No.35599)

Wire Set; Super Conductor; Small Block Chevy with HEI Cap

from

$133.99
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 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) or 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. Available in universal kits and bulk lengths.

Product Features:
  • Less than 50 ohms per foot for superior spark
  • Ferro-magnetic impregnated core creates an effective EMI choke
  • 40 ft. Of Conductor Wound Into A Single Foot Of Wire
  • For high EMI suppression
  • Conductor core features Dupont Kevlar material
  • Proprietary compound sleeves for resistance to high heat/abrasion
