    Manufacturer's Part Number:

    MSD's Universal Spark Plug Wire Sets are available in your choice of black or red wire for a variety of applications and include a spark plug terminal and installed boot with one open end. The set also includes distributor cap boots and terminals so the wire can cut to a specified length and installed with the supplied mini-stripper-crimper.

    MSD's Replacement Spark Plug Wires and Coil Wires are made with the same Super Conductor wire as their universal and pre-made sets, just longer than normal for custom tailoring when you need that extra length.


      • 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.
