Q & A

What's in the Box

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! Plus, the proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears.

This universal 8 cylinder plug wire kit does require assembly, although the spark plug end is already installed. Comes with multi-angle (bendable) plug terminals and boots, including both HEI and socket style distributor ends. Combination stripping and crimping tool also included. Wires are red, boots are gray. 

  • Only 40-50 ohms of resistance per ft.
  • Lowest resistance of any helically wound wire
  • Unique materials and design provides extremely effective Electro Magnetic Interference (EMI) "choke"
  • Keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle
