    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.

    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.

    Rated 5 out of 5 by from Nice wires Much better than the Jegs brand wires I'm replacing. These come with an adequate stripping/crimping tool to aid in assembly. These wires are very long, I used the shortest one supplied for my longest wire.
    Date published: 2016-06-22
    Rated 5 out of 5 by from MSD always ROCK As always MSD products had the correct parts and more than enough wire to build your wires the way you need to run them. The best on the market !!!!!!
    Date published: 2016-08-24
    Rated 5 out of 5 by from Perfect wires The wires were perfect. The instructions were thorough, and they came with a handy tool for crimping and cutting the ends.
