    The Ultimate Spark Plug Wire
    Incredibly Low Resistance Without Electronic Interference

    Features
  • Only 40-50 ohms resistance per foot of wire (lowest of any helically-wound wire)
  • MSD Ignition Copper alloy conductors result in less spark energy loss so more reaches spark plugs
  • Over 40 feet of conductor per foot of wire
  • Conductors are wrapped around ferro-magnetic center cores, which effectively suppresses electro magnetic interference
  • Outer sleeves consist of silicone and synthetic material for a strong resistance to heat, abrasion, and tearing

    Universal Wire Sets
    Routing spark plug wires is an art form. It takes patience and time to route your wires away from the headers, through separators and to the distributor cap. Some wire set fit perfect, but a lot of people want to build their own so they can route them exactly how they see fit. Super Conductor Universal 8.5mm Wire Sets have spark plug terminals and boots installed with the opposite ends open. Distributor cap terminals and boots are included so you can cut wires to desired lengths, then use the included Mini-Stripper-Crimper to install terminals. 2-in-1 Wire Sets include terminals and boots for both socket and HEI-style distributor caps.

    Multi-Angle
    Straight but can be bent close to 90°
    Socket For old socket or points style cap (female Post)
    HEI 90° for spark plug type terminals (Male Post)
