    MSD Ignition 31539 - MSD Universal Spark Plug/Coil Wire Sets Details

    Red Universal Wire Sets

    The new Chrysler and Ford Hemi style cylinder heads being used in Pro Stock racing features a long, skinny tunnel to access the spark plug. MSD's new injection molded tubes are designed specifically for these hard to reach plugs.

    MSD's Universal Wire Sets come with the spark plug terminal and boot installed with the other end open. Distributor cap boots and terminals are included so you can cut the wire to the desired length, then install the terminal with the supplied mini-stripper-crimper. It's a little work, but in the end it will be worth it!

    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.
  • Made in the USA
